QUICK START GUIDE
PLUGGING IN THE OCEANS 12
1. Connect the supplied EHX9.6DC AC Adapter into the 9V jack at the
top of the Oceans 12. Plug the AC Adapter into an AC outlet.
2. Connect your guitar or other instrument into the L IN jack using a
standard 1/4” instrument cable. Connect the L OUT jack to your amp
with another standard 1/4” instrument cable.
3. For stereo operation, connect R OUT to another amp.
DIALING IN A STANDARD REVERB EFFECT
1. Ensure none of the buttons at the top left of the Oceans 12, like TAILS,
are lit. If any of the buttons are lit or blinking, press the button once
to disable it.
2. Ensure that REVERB A is selected by confirming that its SELECT LED
is lit. This LED is located in the center of the unit, in the section labeled
SELECT. If the SELECT LED of REVERB B is lit, press the small white
SELECT button to toggle reverb selection back to REVERB A.
3. Turn on REVERB A by pressing its footswitch located on the bottom
left of the Oceans 12. The white bypass LED should turn on.
4. Rotate the REVERB TYPE knob clockwise to the ROOM setting for a
standard reverb, if not already selected.
5. Set the two smaller knobs to the right of the REVERB TYPE knob to
their middle positions.
6. Set the decay time with the TIME knob, the tone with the TONE knob,
the predelay time with the PREDELAY knob, and the reverb volume
with the FX LVL knob.
CHOOSING A REVERB TYPE
1. Rotate the REVERB TYPE knob in either direction until the desired
REVERB TYPE LED is lit.
2. Check the table on the Oceans 12 below the mini knobs to see the
corresponding parameters that can be adjusted for the chosen Reverb
Type. Turn the mini knobs to experiment with different reverb effects.

5
USING DUAL REVERB
1. At any given time on the Oceans 12, only one of the reverb engines
is selected for editing. The SELECT LED indicates which reverb engine
this is. In general, reverb-editing controls affect only the selected
reverb engine.
2. The default selected reverb engine should be Reverb A, and
accordingly you should see the green LED labeled “A” lit.
3. If Reverb A isn’t already on, turn it on by pressing the left footswitch.
Once it’s on, the white LED in the center moon graphic will be lit.
4. Next, tap the right footswitch corresponding to Reverb Engine B. This
turns on Reverb B, and its blue SELECT LED as well as its
corresponding white Reverb Type LED will light. Because Reverb B is
now the most recently engaged reverb engine, the Oceans 12 makes
Reverb B the currently-selected engine and blinks its blue LED to
indicate this.
5. Now the reverb effects of both Reverb A and Reverb B are applied, in
parallel by default, to your playing. Edits to the knobs and buttons will
affect Reverb B.
6. To change your selection back to Reverb A, you can press the MODE
button. Doing so will switch the selection back to Reverb A, and its
green LED will blink to indicate this.
7. To bypass/engage either of the reverb engines, simply tap their
respective footswitches.
8. See page 28 for detail on dual reverb operation and control.
DUAL REVERB CONFIGURATIONS
1. When dual reverbs are engaged, you can choose which configuration
–parallel or series –in which to arrange them.
2. To edit this, press the button labeled FUNCTION towards the top of
the Oceans 12. It should blink, along with both of the SELECT LEDs,
to indicate that the controls of the Oceans 12 are now performing their
alternate functions, whose graphic labels are colored teal.
3. The alternate functions of the two mini knobs in the REVERB TYPE
table are labeled at the bottom of the table: SRS/PRL and A→B.
Briefly, the left mini knob controls series v. parallel configuration, while
the right mini knob controls series order and parallel mix of the two
reverbs.
4. See page 28 for more details on dual configurations.

6
USING AN EXPRESSION PEDAL
1. Connect your expression pedal to the EXP/FSW jack.
2. While the EXP MODE button is off, the expression pedal acts like a
volume control for your dry signal before it enters the Oceans 12.
3. While the EXP MODE button is enabled, the expression pedal sweeps
all parameters that are assigned to it for the current Reverb Type of
the selected dual reverb.
4. You may assign any knobs you like to be swept by the expression
pedal. Additionally, each knob may have a custom range and direction.
See page 31 of the manual to learn how to create an Expression
Setting for each Reverb Type of both dual reverb selections.
SAVING A PRESET
1. Once you have created a sound that you would like to save, press and
hold the REVERB TYPE knob.
2. After half a second, the PRESET LED will begin blinking rapidly.
Continue holding down the REVERB TYPE knob.
3. After two seconds of holding down the REVERB TYPE knob, the
PRESET LED will stop blinking and light up solid. You can now release
the REVERB TYPE knob.
4. Your preset is saved in the currently selected Reverb Type. You may
save one preset for each of the 12 Reverb Types of Reverb A, and one
preset for each of the 12 Reverb Types of Reverb B.
RECALLING A PRESET
1. Turn the REVERB TYPE knob to the Reverb Type you want to recall.
2. Press and release the REVERB TYPE knob. The preset sound loads and
the PRESET LED lights solid.
3. If you turn a knob or change a button setting, the PRESET LED will
blink rapidly to indicate a preset is loaded but the setting has been
altered.

CONTROLS AND LEDS
- DUAL REVERB SELECT BUTTON AND LEDS -
On the Oceans 12, one of the reverb engines is
always currently selected, regardless of whether
single or dual reverbs are engaged. All of the LEDs
on the Oceans 12 –the Reverb Type LED, the mode
button LEDs, the preset LED, the illuminated
buttons, and the bypass LED -- always reflect the status of the currently
selected reverb engine. The SELECT button allows you to toggle this
selection between Reverb A and Reverb B. When you do, you’ll see that
the LEDs update to the status of the newly-selected reverb engine. You
can also use an external footswitch to toggle between selected reverbs;
see page 30 for more details on external footswitches.
If dual reverbs are engaged, the Oceans 12 will slowly blink one of the
SELECT LEDs to indicate which of the reverb engines is the current
selection. The Reverb Type LED of the corresponding reverb engine will
also blink synchronously. The SELECT button still toggles the reverb
engine selection; pressing it will blink the SELECT LED of the other reverb
engine to indicate that it, now, is currently selected.
Additionally, for convenience, the selection of the current engine will
always default to the last-engaged one. In other words, whenever you
turn on a reverb engine with its footswitch, it immediately becomes the
current selection.
See page 28 for more details and instructions on Dual Reverb operation.

8
- CONTROL KNOBS -
The four knobs on the left side of the Oceans 12 control the main
parameters of the reverb effects. These knobs have different functions
depending on the status of the illuminated FUNCTION button (see the
section about Illuminated Buttons on page 13 for details on FUNCTION).
The top row of white labels specifies the reverb-specific functions of the
knobs, which are active when the FUNCTION button is off. The bottom
row of teal labels specifies the alternate functions of the knobs, which are
active when the FUNCTION button is blinking.
Reverb parameters
REVERB LVL –Wet/dry control that sets the balance between your dry
signal and the reverb effects produced by the Oceans 12. When this
knob is at the minimum position, the output is only your dry signal. As
the knob is turned up, the reverb output increases in volume. As the
knob is turned past 2 o’clock, the dry signal decreases in volume. When
the knob is at the maximum position, the output is reverb only.
PREDELAY –For all Reverb Types except ECHO, SHIMMER, and
RESONANT, the PREDELAY knob sets the pre-delay time for the reverb
block in all Reverb Types except ECHO. Pre-delay allows the musician to
put a time delay between playing a note and hearing the onset of reverb
for that note. The total range of pre-delay is from 0 to 1 seconds. As
you turn the knob clockwise, the pre-delay time will increase. See the
Summary Chart on page 10 to see what Reverb Types have different
settings for this knob.
TIME –In all Reverb Types except REVERSE and DYNA, the TIME knob
controls the decay time of the Oceans 12 reverb. As this knob is turned
clockwise, the reverb time gets longer and longer, reaching infinite in all
modes except SPRING, ECHO, and DYNA when the knob is as far as it
will go. See the Summary Chart on page 10 to see what Reverb Types
have different settings for this knob.

9
TONE –In all Reverb Types, TONE controls the tone or EQ of the reverb
signal, so it’s omitted from the columns of the Summary Chart on the
following page. As this knob is turned clockwise, the sound of the reverb
gets brighter. As you turn TONE counter-clockwise, the sound of the
reverb gets darker.
Alternate FUNCTION parameters
INF LVL –Works as an attenuation control for the infinite/sustain
reverb sound. The default setting is fully clockwise, which corresponds
to no attenuation, or full infinite/sustain volume. The infinitely sustained
reverb volume decreases as the knob is turned counter-clockwise,
reaching zero at fully counter-clockwise.
SEND LVL –Controls the signal level of the FX SEND when the Oceans
12 is in SEND/RETURN FX LOOP mode with a mono setup. See page 15
for details on operating the SEND/RETURN FX LOOP. This is a global
parameter whose value is independent of reverb engine.
LO-FI –Controls the degree of reduction of diffusion and echo density
in the reverb tails. As the diffusion and echo density decrease, certain
qualities of the reverb tail, such as fullness and smoothness, start to
diminish, allowing for creative low-fidelity manipulation of your favorite
reverbs. When the knob is turned fully counter-clockwise, LO-FI turns
off. As the knob is turned clockwise, LO-FI turns on, and the
corresponding LED labeled LF next to the MODE button lights up. The
degree of the LO-FI effect is increased as the knob is turned clockwise.
TIDE –Controls the amount of TIDE effect applied to the reverb output.
When stereo outputs are used on the Oceans 12, TIDE subtly modulates
the pan of the stereo output to gradually evolve the sound stage. When
the knob is turned fully counter-clockwise, TIDE turns off. As the knob
is turned clockwise, TIDE turns on, and the corresponding blue LED
labeled TIDE next to the MODE button lights up. The frequency of the
modulated pan is slowly increased as the knob is turned clockwise.

- REVERB TYPE KNOB, PRESET LED, AND MINI KNOBS -
REVERB TYPE Knob
This knob is a rotary encoder that selects which of the Oceans 12’s Reverb
Types is active. The list ranges from ROOM at the top to RESONANT at
the bottom. You can choose which Reverb Type is selected for each reverb
engine.
One preset can be saved for each Reverb Type using the REVERB TYPE
knob. For details on preset operation, see page 36. The PRESET LED
provides a visual indication for the current preset state:
PRESET LED Off: You are in What You See Is What You Get
(WYSIWYG). All current knob positions represent the effect being
generated.
PRESET LED On: The preset is loaded for the currently selected Reverb
Type.
PRESET LED Blinking: There are two situations where the PRESET
LED blinks: 1) while saving a preset or 2) changing a knob or button
setting after loading a preset. If you load a preset and then move a
knob, the new knob position takes over for only that particular
parameter and the PRESET LED blinks. If you return the recently moved
knob to the position that is saved in the preset, the PRESET LED lights
solid again.
Miniature Parameter Knobs
To the right of the REVERB TYPE knob are two mini knobs whose functions
change depending on the selected Reverb Type, mode, and status of the
illuminated FUNCTION button. On the face of the Oceans 12, below the
mini knobs, there is a table listing the available mini knob functions for
each Reverb Type. Detailed descriptions of mini knob functions start on
page 22 of this manual. When the FUNCTION button is blinking, the mini
knobs control the teal-highlighted parameters at the bottom of the Reverb
Type table.

13
- ILLUMINATED BUTTONS -
EXP MODE Button –When this button is lit, EXP MODE is enabled. When
an external expression pedal or control voltage is connected to the
EXP/FSW jack on the rear of the Oceans 12, you can control any
combination of knob parameters with your foot. When the EXP MODE
button is disabled (button is not lit), the external expression pedal acts as
a volume pedal for the dry signal and the signal into the reverb effect.
This button is also used to set up Expression Settings (see page 31 for this
procedure).
MOMENT Button –Enabling MOMENT changes the functions of the
REVERB A and REVERB B footswitches to only allow the reverb effects
while the footswitch is pressed down. The reverb effects are bypassed
when the footswitch is released. When MOMENT is disabled, the REVERB
A and REVERB B footswitches work like normal latching footswitches,
toggling between bypass and effect modes with each press and release.
TIP: Use the MOMENT button in conjunction with tails to pinpoint exactly
which notes or segments of a phrase receive reverb effects. However, be
aware that, by default, holding down the REVERB A or REVERB
footswitches while their engines’ respective TAILS are on triggers infinite
sustain. To toggle infinite capability and save it for an external footswitch,
see the Footswitches and LEDs subsection on page 18.
TAILS Button –When TAILS is enabled, the reverb continues to play
after its engine switches to bypass, with the decay time set by the TIME
knob. Switching the reverb engine to bypass occurs by either disengaging
it with the footswitch, or switching the currently selected reverb engine
with the MODE button. Anything you play after entering bypass will not
go through the reverb effect. If the pedal is set for infinite decay (i.e. the
TIME knob is set to maximum), the reverb continues until you turn down
the TIME knob or switch to a different Reverb Type. When TAILS is
disabled, all reverbs stop as soon as their engines are bypassed.
FUNCTION Button –This button selects which set of parameters –
primary or alternate -- is controlled by the main knobs and the mini knobs.
When FUNCTION is pressed, the button and the two SELECT LEDs will
blink concurrently, and all other LEDs and controls on the Oceans 12 will
be disabled, to indicate that you are now editing alternate parameters.

14
For the main knobs, the alternate functions are INF LVL, SEND LVL, LO-
FI, and TIDE, respectively. For the mini parameter knobs, these functions
are SRS/PRL and A→B. More details about these alternate knob
parameters can be found in the Dual Reverb section on page 28.
The FUNCTION button can also toggle signal splitting, where Reverb A is
sent to L OUT and Reverb B is sent to R OUT, as illustrated in the diagram
below.
If the FUNCTION button is held down for 2 seconds while the FUNCTION
mode is not already on, all of the Oceans 12’s blue and green LEDs will
start to blink rapidly, indicating that the two signals of the two reverb
engines are now being split into L and R outputs. To disable signal-splitting
and bring the Oceans 12 back to regular stereo operation, hold down the
FUNCTION button when FUNCTION isn’t already on. The blue and green
LEDs will again start blinking rapidly to indicate that the turn-off procedure
has begun. After 2 seconds, signal splitting will be disabled. The on/off
status of this routing scheme is remembered even after power-cycling.
Signal splitting is disabled if the SEND/RETURN FX LOOP is on.

15
- SEND/RETURN FX LOOP -
The Oceans 12 has the ability to create a special, wet, mono FX LOOP
either before or after the reverb block. See the following diagram:
The SEND is output through the R/SEND OUT jack. The return is
connected to the R/RETURN IN jack. Tip: useful for when you’d like an
effect in your chain, for example a fuzz or filter, to affect only the reverb
tails, i.e. without affecting your dry signal.
The amount of signal routed to the SEND path is controlled by the SEND
LVL, the alternate parameter of the PREDELAY knob. This knob controls
the SEND LVL whenever FUNCTION is on. (See page 13 for details on
the FUNCTION button). When the knob is turned fully counter-
clockwise, the SEND LVL is zero. The SEND LVL increases as the knob is
turned clockwise, reaching unity when fully clockwise. Note: the default
value of the SEND LVL is zero. When a SEND/RETURN configuration is
active, be sure to adjust the SEND LVL to your desired amount.
The status of the Send/Return FX loop is always either pre-reverb, post-
reverb, or OFF (i.e., regular stereo operation) . If the status is either pre-
reverb or post-reverb , the green S/R LED on the bottom-left of the unit
(pictured below) will be lit after the pedal is powered up. The Oceans
12 will remember the FX loop status, even after removing power.

16
To toggle pre-reverb SEND/RETURN, power-cycle the Oceans 12 while
holding down the FUNCTION button. If the SEND/RETURN status was
previously post-reverb or OFF, it will now be pre-reverb. Similarly, if the
SEND/RETURN status was previously pre-reverb, it will now be turned
OFF.
To toggle post-reverb SEND/RETURN, power-cycle the Oceans 12 while
holding down the TAILS button. If the SEND/RETURN status was
previously pre-reverb or OFF, it will now be post-reverb. Similarly, if the
SEND/RETURN status was previously post-reverb, it will now be turned
OFF.
The SEND LVL is a global parameter that will not be tracked by presets.
The configuration (pre vs. post) of the Send/Return as well as its SEND
LVL, however, are remembered across power cycles.
Turning on the Send/Return FX Loop also disables the signal-splitting
stereo control of the FUNCTION button.
If the configuration of Send/Return FX Loop is pre-reverb , but nothing
is inserted into the R/RETURN jack, the FX Loop connection is shorted
and the send channel connects directly to the return for regular mono
operation.

17
- MODE BUTTON AND LEDS -
Each Reverb Type on the Oceans 12 has either two or three unique modes
of operation. Pressing the MODE button cycles through these available
modes. The LED labels 1, 2, or 3 show the current mode. When you switch
Reverb Types, the Oceans 12 will recall the last mode you were using in
that Reverb Type.
Below the three numbered LEDs are two LEDs labeled LF and TIDE. These
two LEDs indicate whether LO-FI and/or TIDE, respectively, are currently
on. LO-FI and TIDE are activated and controlled by turning on the
FUNCTION button and adjusting the main knobs whose alternate labels
are LO-FI and TIDE.

18
- FOOTSWITCHES AND LEDS -
The Oceans 12 has two footswitches which perform the same functions
for their respective reverb engines. The left footswitch controls Reverb A,
and the right footswitch controls Reverb B. Each footswitch has the
functionalities described below.
Footswitch Functions
BYPASS –The BYPASS functionality of the footswitch works like that
of a standard latching footswitch when the MOMENT button is not lit:
press and release to toggle between bypass and effect modes. When
the center white LED in the Oceans 12 graphic is lit, at least one of the
reverb engines is engaged and the unit is in effect mode.
If the MOMENT button is lit, then the selected reverb engine is normally
in bypass mode unless you press and hold the footswitch, at which point
it goes into effect mode. Release the footswitch and it returns to bypass
mode.
TAP –In ECHO reverb, press and release the footswitch two or more
times to set the delay time with your foot. The tap time and the current
MODE setting determine the actual delay time. After tapping in a delay
time, you may cycle through the MODE settings to find the desired delay
timing. The blue TAP LED at the bottom left of the Oceans 12 (pictured
below) will blink at the selected echo rhythm of your tapped tempo.
INFINITE –If TAILS is on, then press and hold one of the footswitches
to ramp up the reverb decay time of the associated reverb engine to
infinitely sustain. The white INF LED at the bottom left of the Oceans 12
(pictured above) will blink rapidly to indicate that infinite sustain is
engaged. Release the footswitch to ramp back down to the current
feedback setting. You may continue playing your instrument while the
infinite reverb decay is sustaining; the Oceans 12 will apply fresh reverb
from the second reverb engine to your new playing, indicated by the
rapid blinking of its SELECT and Reverb Type LEDs. While INFINITE is
sustaining, you may edit any of the knobs –these control changes will

19
be applied to the fresh reverb of the second reverb engine, and will be
remembered when you switch back to that reverb engine.
You may also use an external footswitch to trigger INFINITE sustain.
See page 30 for details on external footswitch functionality.
You can also disable the local footswitches’control of TAP and INFINITE
functions. (The functions will still be enabled via external footswitch).
Tip: This is useful if you don’t use an external footswitch and you’d like
to prevent accidental tempo taps from occurring, or if you’d like to use
the footswitches in a held-down capacity (e.g., with MOMENT and
TAILS) without triggering the INFINITE sustain .
To disable/enable local footswitch control of TAP and INFINITE:
1. Unplug the Oceans 12 from power.
2. Press and hold the REVERB B footswitch while plugging power
back in to the Grand Canyon.
3. The BYPASS LED will flash 7 times if tap tempo and infinite are
disabled. The LED will flash 2 times if tap tempo and infinite are
enabled.
4. If the Oceans 12 is reset to factory defaults (see page 38), the
footswitch’s tap tempo and infinite functionality will be enabled.
KICKING THE SPRING TANK –In SPRING reverb, if “TAILS” is on
(see “Controls” on page 3) in Mode 1 (Fender® 6G15) in either reverb
engine, quickly double tap the footswitch to "kick" the emulated spring
tank. If an external footswitch is connected to the EXP/FSW jack, then
you must use that one instead of the internal one (TAILS must still be
on). This will send a loud bouncy jolt through the OCEANS 12, as it
would a real spring reverb unit. This action can be performed when
using dual reverbs in any configuration (i.e., both series and parallel).

20
CONNECTIONS
L INPUT Jack –This ¼” jack is either the mono audio input or the left
stereo input to the Oceans 12. In mono, the input impedance is 1M. In
stereo, the input impedance is 2M.
R INPUT Jack –This is the right input jack in a stereo setup. This input
can also be the RETURN signal if using SEND/RETURN mode (see page
15). The input impedance is 2M.
L OUT Jack –Use this output for a mono setup. In a stereo setup this is
your left output. The output impedance is 550.
R OUT Jack –This is the right output jack in a stereo setup. This output
can also be the SEND signal if using SEND/RETURN mode (see page 15).
The output impedance is 550.
Combo EXP/FSW Jack –This input jack accepts either an expression
pedal or an external footswitch. The Oceans 12 can automatically
differentiate which of the two is connected.
EXP –Connect an expression pedal with a TRS plug to this jack to allow
external control over any of the Oceans 12’s knobs, or use it like a volume
pedal on the dry signal before it hits the reverb effects. See page 31 for a
description on how to set up and control the Oceans 12 with an external
expression pedal.
The polarity of the expression pedal’s plug must have the sleeve connected
to the heel position (usually GND), Ring connected to the toe position and
the Tip connected to the wiper. The nominal expression pedal impedance
is 10kΩ though most other values will work fine. Please do not go below
6kΩ on your expression pedal’s potentiometer impedance. Some
