ECCOS DELAY/LOOPER
THE KEELEY ECCOS - FLANGE MODULATED TAPE DELAY / LOOPER
Tape-Flanged Delay Trails. That’s what makes the ECCOS delay pedal unique; a new style of
tone-modulation that isn’t pitchy. It’s the sound of just the echoes being flanged with vintage
reel-to-reel tape decks. The shape and tone of your repeats are constantly changing, creating
lush movement to your delay trails! Listen as your delay trails move with flanged tonalities that
are beautifully filtered and sound tone-modulated, not just pitch modulated. Simply adjust the
Rate and Modulation parameters to hear the flanged delay trails mixed with your pure analog
blended guitar. Modulation without undue pitch bending.
The ECCOS is also a Looper. Record and playback loops while you play live. ECCOS features like
Reverse, Half Speed, and Play-Once are easy to use creatively. Create guitar magic using the
delay with its own tap tempo (up to 1.5 seconds); all while layering on endless loops of audio.
The ECCOS offers loop times of up to 120 seconds in mono, and up to 60 seconds in stereo.
The Keeley ECCOS features true stereo processing with mono and stereo inputs and outputs.
Uber-clean, all-analog audio for the pure guitar dry/blend. Experience next level audio DSP
using the Dream quad 24/56-bit processor. There are nine adjustable controls for crafting the
tone of the delay trails. Manual or remote operation of looper, bypass, presets, and tap tempo.
Dynamically assign controls to be used with a foot expression pedal. Switch back and forth
between the Delay and Looper to choose custom delay sounds and then record additional
layers, hands-free, while looping.
PLUG IN AND PLAY YOUR GUITAR!

TIME - Adjusts delay time manually from 5ms to
1.5 seconds.
BLEND - Adjusts effect level, blend in delay with
your clean guitar tone.
DEPTH - Depth of Delay Modulation, up to 13ms.
Set high to achieve chorus-like modulations.
Turning the depth to zero produces a clean delay
tone.
FEEDBACK - Adjusts the number of delays or
repeats. FDBK is also a push button switch. Tap the
FDBK knob once to enter preset selection mode.
Press and hold FDBK to access secondary controls
like TONE or REGEN, or use the MODE select new
tempo subdivisions. Quickly double tap the FDBK
knob to switch between Looper and Delay modes.
You can even use your foot while playing live!
RATE - This controls the rate or speed of your
modulated delay trails. Setting this slow will create
slightly comb filtered delays. Fast rates can be used
to get rotary speaker effects. The sine wave LFO
modulation goes from 0 to 15 Hz.

SECONDARY DELAY CONTROLS

MANUAL (Flanger Time) - Subtly changes the
delay time of the flange. Ranges ~0 - 13ms. With
longer times, the delays become more chorused.
Set at minimum by default.
VIBE (Modulation Style) - Flanged delay trails are
created by producing two repeats that are blended
together. The VIBE knob controls the clean portion
of your delays. Turn CCW for pitch vibrato. Turn CW
for flanging repeats. Set at max by default.
TONE - Tone control for the repeats. Set it high for
a sweet high-pass sheen. Set it lower for a warm,
tape style high-end roll off. Set at noon by default.
REGEN (Flanger Regeneration) - Controls the
amount of flanger feedback. Increasing this control
will give you deep flanging effect for your delays.
Set at minimum by default.
SUBDIVISIONS - Like all secondary controls,
hold down the FDBK knob. While knob is held
down, toggle the mode switch to set delay-time
subdivisions: Quarter, Dotted Eighth, Eighth, or Triplet.
The Status LED will blink the current subdivision while
FDBK is held down. Set at quarter note by default.
Hold down the FDBK knob to access
secondary controls.

ECCOS DELAY/LOOPER
ENTERING LOOP MODE:
Place the ECCOS in looper mode by using the
MODE toggle switch or by double tapping the
FDBK knob with your foot. The Looper LED will
light to indicate which mode is active.
RECORD/PLAY/STOP - To start recording a loop, press the
BYPASS (Record) switch and begin playing. The BYPASS LED
turns red. After playing, press the BYPASS (Play) switch again
and playback will start. The BYPASS LED will turn blue.
To stop the looper, double tap the BYPASS (Stop) switch. The
STATUS light will remain blue indicating that there is a stored
recording ready for playback.
OVERDUB - To start an overdub from Play mode, simply tab
the BYPASS switch again. The BYPASS LED will turn red to
indicate recording. When you’re done recording, press the
START switch to go back to playback mode. The LED will
once again turn blue.
UNDO/REDO - To undo your last recording, press and hold
the FDBK knob for 1 second. If you are recording your first
loop, this will silently delete the track. If you completely stop
the loop, you cannot undo your last overdub as it has been
saved to memory at that point.
LEVELS - Adjust the volume level of playback with the Looper
Level (DEPTH Control). If no ECCOS delay effect is desired
while looping, simply turn down the BLEND knob.
Note: The ECCOS delay side can also be turned off independently.
DELETING LOOPS - To delete a loop, switch to Loop Mode
(you must be in loop mode to delete loops). Double tap &
hold BYPASS to delete the loop. The STATUS and BYPASS
lights will flash twice and then turn off indicating you
have cleared the memory and recording. Silent Erase - If
it is your first recording in loop mode, and you are still
recording, you can undo it by holding down the FDBK
knob, giving you a way to silently delete that first track.
The STATUS LED turns blue and will flash once at the
beginning of your loop. This lets you know where your loop
starts.
Note: The Eccos delay sounds work in looper mode! The TONE
control adjusts the tone of your delays. Blend, Feedback, and
Time work for the delay effect as well.

EXTENDED RECORD MODE

To hear your loop in half speed, double tap the REVERSE/
HALF SPEED switch. If you are in playback you will hear
your recording an octave down and at half speed. The
LOOPER LED will rapidly flash letting you know that
you’re in half speed mode. You can enter this mode during
playback or recording for creative effect. Record while
in half speed, then double tap, and anything you have
recorded will now sound an octave up and in double-time!
To hear your loop in reverse, press and hold down the
REVERSE/HALF SPEED switch while you are playing or
recording a loop.
If you are recording an overdub and then you press and
hold the REVERSE/HALF SPEED switch (for Reverse),
playback will sound in reverse and anything you record
with your guitar will playback in reverse when you let go
of the REVERSE/HALF SPEED switch!
Extended Record Mode - The Eccos comes from our factory with Undo/Redo enabled and with 60 seconds
mono recording time. To get 120 seconds of looping time simply remove power and then press and hold
down the FDBK knob while applying power again. This will remove the Undo/Redo feature and give you the
maximum recording time.
This also engages Sound on Sound Mode (See pg. 10)
What makes the ECCOS an effective Delay / Looper is
that you can go back and forth between the Delay and
Looper modes while looping. To go between modes
simply use the MODE toggle switch, or Double Tap the
FDBK knob with your foot. Either operation will change
between Looper and Delay modes. Now, while looping,
you can go back to Delay mode to tap in a new delay
tempo or even change delay presets!
For example, you can start a loop with Preset 1. Then,
while playing back a loop, you can double tap the FDBK
switch and go back into Delay mode and select a new
preset. Double tap FDBK and go back into Looper
mode. Now when you record an overdub, you will have
your preset delay and modulation tone carry over to
looper recording.

ECCOS DELAY/LOOPER
PRESET SELECT MODE - To enter Preset Select
Mode (while in delay mode), quickly double tap
BYPASS or tap the FDBK knob once. Preset LEDs will
begin to flash. The TAP switch or MODE select switch
advances through the presets. Tap BYPASS again to
select the preset currently flashing. Hold BYPASS to
overwrite the selected preset.
CHANGES TO A PRESET - Any changes made to a
parameter will turn OFF the preset LED. Double tap
the BYPASS switch again to once again enter preset
select mode, then hold the BYPASS switch to enter
save mode, cycle through the presets by using the
TAP or MODE switch, then hold the BYPASS switch
again to save the changes made to the selected
preset.
The ECCOS features 3 preset locations. In addition,
you can access a What You See Is What You Get
(WYSIWYG) mode by entering Preset Select Mode,
then scrolling through the preset locations until all
3 Preset LEDs are blinking, then select it by tapping
the BYPASS switch. This is a great way to exit any of
the three preset settings and go back to where the
controls are currently set.
SWITCH PRESETS WHILE LOOPING - Switch
to Delay mode, single tap the FDBK knob, cycle
through the presets by pressing TAP, then engage
the new preset by tapping the BYPASS switch.
Note: When the WYSIWYG preset is selected, it will
recall all of the previous (non-preset) secondary and
expression control positions. All of the main controls
are set to the pots current positions. Similar to a
preset but only for the secondary and expression
controls, the pots are read at their current positions.
The three lights in the middle of the ECCOS are
preset indicators, which will correspond with the
currently engaged preset. In WYSIWYG mode, all
three are constantly lit.
CREATING AND SAVING PRESETS

SOUND ON SOUND MODE
INDEPENDENT SWITCHING
The ECCOS now features Sound on Sound
Mode! Sound on sound mode lets you record
without erasing the original loop. The volume
of the loops degrade over time, recreating a
vintage reel to reel recording technique. To set
the decay of the loops, hold down the FDBK
knob and adjust the Depth control. This alt
control comes in handy when using Sound on
Sound Mode.
The ECCOS features advanced independent
switching. The Delay or the Looper can be
turned on and off independently. You can start
the Looper with our without a Delay Setting.

ECCOS DELAY/LOOPER
TRAILS OR TRUE BYPASS
STATUS LIGHTS
STEREO, PING PONG, ETC.
RUNAWAY FEEDBACK OSCILLATOR
When bypassing the unit, the ECCOS can be set to let delay trails repeat or to stop them immediately. No trails is
equivalent to true bypass; trails requires and uses a top shelf, Keeley Electronics approved output buffer.
TRAILS - Hold BYPASS + Hold TAP for 2 seconds.
The BYPASS And STATUS LEDs will flash two times to show the change was saved. Default setting is true bypass.
Status Light steady = A loop is in memory. Blinks once at the start of a loop.
Looper Light flashing = Loop is playing at half speed.
Bypass and Status Lights flash twice = Loop has been successfully deleted.
Bypass and Status Lights flash twice = Expression controls have been cleared.
Status Light constant blink = You are in expression pedal assign / unassign mode.
A slight stereo field is created when simultaneously using both outputs. The Stereo Out is slightly modulated to
give a stereo impression. True stereo ping pong only occurs when using two amplifiers. Stereo ping pong only
works in subdivisions.
Note: In stereo mode, the quarter note is on the stereo output and the subdivision is on the mono output.
Press and hold TAP to engage maximum feedback - Perfect for endless repeats at the press of a button!
To adjust the volume of the runaway feedback oscillator, hold TAP and adjust the FDBK knob while in delay mode.
Note: This can only be set with the FDBK knob, and not with an expression pedal.

REMOTE/LOCAL OPERATION
For Remote Bypass/Tap Tempo
FOR MOMENTARY SWITCHES
Hold TAP - Apply Power
If you are using momentary switches for turning
on and off the pedal, then hold TAP while applying
power to the DC jack. The pedal is in REMOTE
MOMENTARY MODE. The BYPASS LED is red in
Effect Mode.
FOR LATCHING SWITCHES
Hold BYPASS - Apply Power
If you are using a latching (relay) system or foot
switch, hold BYPASS then apply power to the 9 volt
DC jack. The pedal is in REMOTE LATCHING MODE.
The Bypass LED is red in effect mode. The BYPASS
switch on the ECCOS still functions for selecting
presets.
Tap Tempo always requires momentary switching.
You cannot use a latching switch for tap tempo.
Note: Deleting of Loops must be done using the
BYPASS switch on the unit when using Remote
Latching Mode.
ELECTRICAL CONNECTIONS FOR REMOTE OPERATION
Use a TRS / stereo cable.
Tip = TAP Ring = REMOTE BYPASS
You can also use a mono guitar cable for tap tempo and
the BYPASS will work as normal on the pedal. This way
you can use a remote tap tempo box and keep your
ECCOS at the top of your pedalboard.
Tap tempo via the jack is always active.
ALL WET MODE
Hold FDBK + Hold BYPASS while applying power to the
unit. The ECCOS can be made all wet for use with an
amplifier with a parallel effect loop.
FACTORY RESET
Hold FDBK + Hold BYPASS + Hold TAP
while applying power to the unit.
All LEDs will flash in succession and all controls,
secondary controls, modes, memory and presets will
return to default settings.
You will see all of the lights on the ECCOS cycle,
indicating that the Factory Reset is complete.
Note: When making these adjustments, it helps to place
the ECCOS on a flat surface, such as a pedalboard or a
table top.
ADVANCED SETTINGS
Power must be removed and reapplied for the following settings

EXPRESSION PEDAL INPUT
You must use a TRS (stereo) expression pedal with the
ECCOS. If you use a mono cable (or volume pedal), the
ECCOS will not power on.
When a TRS (stereo) expression pedal is inserted, the
expression pedal defaults to controlling the BLEND
control of the delay.
Note: Plugging a mono cable into the TRS EXP. PEDAL
jack will allow the control of the FDBK switch with a
momentary switch.
CLEAR ALL EXPRESSION SETTINGS
To clear ALL expression pedal settings, enter Expression
Pedal Mode by holding FDBK for 2 seconds. Once in
Expression Pedal Mode, hold BYPASS for 2 seconds to
clear ALL expression pedal settings and reset them to
default. Once finished, exit Expression Pedal Mode by
holding FDBK for 2 seconds.
