CONGRATULATIONS
on your purchase of Duck Tail Delay, a classic T-Rex delay pedal descended from our legendary Replica family of delay effects for guitar and bass.
Duck Tail Delay comes with everything you’d expect from a T-Rex pedal
– gorgeous vintage tone, fine craftsmanship, and the perfect mix of controls, including the brilliant tap tempo control that has made our delays
staples on pedal boards everywhere.
Plus, we’ve added a tape delay mode and a sophisticated ducking mode
that lets you control your delay just by the way you pick.

USING YOUR DUCK TAIL DELAY
The main controls on your Duck Tail Delay are the DELAY, FEEDBACK,
TIME and LEVEL knobs, while the TAP button, the MODE (DUCK,TAPE,
CLASSIC) switch, and the SENSITIVITY knob provide further control.
DELAY determines the mix of direct and delayed signal. Turn it down for
a subtler natural effect, and crank it up for doubling or freaky long delay
effects.
The FEEDBACK knob lets you control the number of times a sound is
repeated – from just once to an almost infinite loop.
TIME determines the rate of your delay repeats and can be adjusted
from 10 to 1,000 ms. TIP: to experiment, try tuning in a classic 50s slapback sound by combining a fast time with a low repeat value.
MODE switch lets you switch between the new DUCK mode, a vintage
TAPE delay sound, and a CLASSIC delay effect.
DUCK mode lets you control how much delay you get dynamically, depending on how hard you pick the strings. Play with a light attack, and
the delay is fully activated – making it perfect for quiet, more sensitive
passages. Pick harder, and the delay effect decreases, so you can play
heavy chords and sharp staccato lines without any echoing clutter.
The SENSITIVITY knob lets you control how hard you have to pick before
the delay effect ramps out.
The TAP button activates your pedal’s TAP TEMPO function. To automatically adjust the tempo of your delay to match the tempo of the song
you’re playing, just use your foot to tap the button along with the beat.
Note: The INPUT GAIN knob on the side of your Duck Tail Delay eliminates overdrive distortion caused by too high of an input signal. Keep it
set just below where the red light comes on.
