instant Auto-Flange
feature.
See page 9 for in-depth
explanation of the Auto-
Flange feature.
WOBBLE
Adds a random speed
modulation element to the
delayed Lag Deck. At lower
settings, the variations are
mild, covering the speed
changes that a recording
engineer might use to create
time-varying flange effects. At
higher settings the variations
become more extreme.
BLEND
Sets the relative mix level of the
two tape decks.Turn lower to
blend in more of the Reference
Deck, which can serve to tame
your doubletracking effect. Turn
higher to blend in more of the
delayed Lag Deck. At 12:00, both
decks are equally mixed to the
output.
SATURATION
Sets the amount of tape
drive by adjusting the
preamp gain. At low
levels, a subtle harmonic
enhancement occurs,
increasing the dynamic
compression and
distortion as the knob is
turned up.
VOLUME
Controls the output
volume of the Saturation.
BLEND TYPE
Achieve subtle differences
in tonality and low-end by
adjusting internal phase
and routing.
Sum - Decks are in phase.
Invert - The Lag Deck is
phase-inverted.
Bounce - Right channel
of the Lag Deck is phase-
inverted and bounced
to the left channel input
creating a ping-pong-like
stereo effect, or a double-
repeat effect when using a
mono output.
LAG TIME
Sets the delay offset between
the Reference Deck and the
delayed Lag Deck, creating a full
range of doubletracking tape
effects. Transition from tape
flange on the first half of the
knob, to tape chorus, slapback,
and then tape echo with a
maximum 500mS delay.

LOW TRIM

filter for subtle low
frequency tailoring.
Full bandwidth at
minimum setting.
HIGH TRIM
Controls a shelving
filter for subtle high
frequency tailoring.
Full bandwidth at
minimum setting.
DOUBLETRACKER
BOOST/CUT
Boosts or cuts the
Doubletracker effect by up to
3dB to allow for precise level
matching. Full boost at max,
unity gain at 12:00.
AUTO-FLANGE TIME
Sets the sweep time for the
press-and-hold Auto-Flange
feature. Low settings are faster,
and higher settings are slower.
See page 9 for in-depth explanation
of the Auto-Flange feature.
WIDE STEREO MODE
Generates a wide stereo
image. Turn past 12:00 to send
the Reference Deck to the Left
Out and the delayed Lag Deck
to the Right Out. Disable by
turning to left of 12:00. The
Blend control then acts as a
Pan control by adjusting the
relative levels of the decks.
Automatically disabled with
mono output. If the input is
stereo it is summed to mono.

Lag Time Ranges
• For a more subtle effect, reduce the Blend knob to favor the Reference Deck.
• Changing from Sum to Invert mode will change the response of the low frequencies
for another tonal possibility.
• Increase Lag Time to get a wider chorus sound.
3 to 50 ms
Longer Lag times result in a
thicker sound as if there are
two performers playing the
same part. Increasing the
Wobble control adds more
movement and separation
between the two decks.
• Set the Blend to 50/50 (12:00) for the most pronounced flange effects.
• Through-zero effects are more intense when using distorted guitars or high-bandwith
input signals. Add some Saturation to enhance a clean guitar input. Experiment with the
difference between Sum and Invert modes in this area for very different experiences.
• For an inverted flange that doesn’t cancel completely, try setting the Blend lower than
12:00 to favor the Reference Deck, or turn the Lag Time to around 10:00 so the delayed
Lag Deck doesn’t cross through zero.
• Try minimum Lag Time and set Blend to maximum (no reference deck mixed in) for a
random vibrato when Wobble is at maximum.
-.3 to 3 ms
Very short Lag times produce
a moving comb-filter/flange
effect that goes ‘through-
zero’ when the lag time is
set less than zero. A static
filter effect is achieved when
the Wobble is turned to
minimum.
50 to 150 ms
First heard in the rock ‘n roll
records of the ‘50s, slapback
echo produces the sound of a
performance in a large space
where the echo is reflecting
back from an opposing wall.
• With the Blend past 12:00, the slap can be louder than the input. Try this with shorter
slap times.
• Try slap echoes with the Blend Type in the Invert position. This represents a true
physical reflection where the sound waves invert as they bounce off a wall. It can add a
‘3D’ feel. Add some mild modulation to create subtle movement in the echo sound.
• Try Bounce mode for a thicker slap that has two distinct repeats.
150 to 500 ms
Longer Lag times can create
delays suitable for soloing
or adding some ambience
or rhythmic effects to your
playing.
• Try lower Blend settings for a distant echo effect. Add some Wobble for a random
modulation-delay effect.
• Bounce mode will create two repeats to further fill out the soundfield.

The Saturation knob allows for a wide range of input signals to provide a nicely
saturated tape effect. The overall range of Tape Saturation is rig dependant.
Depending on your application and your input signal level, the affect of the tape
saturation will vary. Below are some general guidelines.
When using Deco in front of an amp, lower output single coil guitar pickups
will experience a rich harmonic enhancement and a lighter overdrive effect.
When using Deco in front of an amp, higher output humbucker pickups
will experience heavier overdriven harmonics when the Saturation knob is
turned to maximum.
Deco accepts up to +8dBu of input signal. When using Deco in a hot effects
loop of a guitar amp, or when driving Deco with a hot output from a synth
or mixer insert, you should reduce either the Saturation knob or your input
level. The signal will still experience high levels of tape saturation at these
lower settings due to the hotter signal input level.

Expression Input Modes
The EXP jack on your Deco is set up for Expression Pedal from the factory.
To change the Expression Input mode, hold down both Saturation Bypass
and Doubletracker Bypass switches while powering up. While holding
down, turn the Saturation knob to one of three ranges shown below.
HOLD BOTH AT POWER UP while turning the
SATURATION knob to set Expression Input Mode
EXPRESSION PEDAL
Set to Expression pedal mode
and connect a standard TRS
expression pedal for control over
any knob.
To assign the knob controlled
by the expression pedal: Power
down your pedal. Hold the TAPE
SATURATION BYPASS footswitch
during power up, while turning
the knob you’d like to assign.
The maximum position the knob
is turned up to becomes the
expression pedal “toe down”
maximum value.
FAVORITE SWITCH
Set to Favorite switch mode and
plug in a Favorite switch to save
and recall a favorite preset. To
save a favorite setting, press and

and connect an external
tap switch to tap in your
Lag Time. Tapping quarter
notes sets the Lag Time to
8th notes.

Bypass Modes
HOLD BOTH AT POWER UP while turning the
BLEND knob to set Bypass Mode
Deco is set up for True Bypass from the factory. To change this mode,
hold down both Saturation Bypass and Doubletracker Bypass switches
while powering up. While holding down, turn the Blend knob to one of two
ranges shown below.
TRUE BYPASS
Set here to use our True
Bypass circuit, which is simply
a mechanical relay to switch
the input signal directly to
the output, with absolutely no
components attached.
BUFFERED BYPASS
Set here to use our high-quality Analog Buffered
Bypass. This circuit features a 1Meg input
impedance, keeping the character of your guitar
pickup unaltered. The output impedance is 100
Ohms and can drive hundreds of feet of cable
without coloring your sound.

Press and hold the Doubletracker Bypass
footswitch to achieve a recording studio-inspired
Auto-Flange effect. This engages a “virtual audio
engineer” manning the faders and tape reels to
create a smooth and predictable through-zero
flange experience on the fly.
When the Doubletracker Bypass footswitch is
held down, the delayed Lag Deck is set just a bit
behind the Reference Deck. Then, the Blend and
Lag controls are simultaneously varied as the Lag
Deck ‘catches up’ to the Reference Deck at a speed
controlled by the Auto-flange Time setting. After
releasing the footswitch, the controls are smoothly
returned to their previous settings.
The 1/4” input can be set for either mono input or
TRS stereo input. The pedal ships in mono input
configuration from the factory. Here’s how to
change the input configuration:
Remove the back cover of your pedal. On the left
side of the circuit board, you’ll see a jumper that
can be set in two positions. Place the jumper on the
left 2 pins for TRS stereo input. Place the jumper
on the right 2 pins for mono input.
In order to use the TRS stereo input,
you’ll need a TRS stereo input adapter
like the one shown below.
