TAPE ECHO
HANDCRAFTED IN DENMARK
CONGRATULATIONS ON YOUR PURCHASE OF THE T-REX REPLICATOR!
The Replicator is a true tape echo with modern features that were not available on
tape echoes in the past.
A tape echo works by recording and playing back audio on a magnetic tape loop
run by a motor. The time it takes for the tape to go from the record head to the
playback head(s) will determine the delay time. A feedback circuit sends the
delayed audio back to the recording head for multiple repetitions that fades over
time.
On a tape echo, the delay time can be shortened by either turning up the motor speed or placing the playback head(s) closer to the record head. Longer delay
times require a slower motor speed or longer distance between the record head
and the playback head.
There are two playback heads on the Replicator, each mounted in a fixed position
in relation to the record head. Head2 is placed at exactly half the distance from the
record head as Head1, so the delays coming from Head2 will always be half as long
as the ones from Head1. The delay time is varied by changing the speed of the motor that drives the tape reel.
The output of Head1 is slightly louder than Head2´s. You can use Head1 for lead
lines with longer delay times, Head2 for more subdued/short echos or both for a
very special dual delay sound that alternates the loudness of the repeats, giving
the effect a different “rhythmic” feel.
CONTROLS
Master Volume: Controls the overall output level of the pedal. At the maximum setting, the output is boosted appr. 8dB.
Chorus: Controls the depth of the modulation effect that is applied when the chorus
is switched ON. Turn this up for deeper pitch modulation of the delay signal(s).
NOTE!: Please see “Helpful hints” below for more details.
Saturation: Controls the recording level of the rec. head. Depending on how strong
the incoming signal is, the record head can be driven into saturation when this control
is turned up. The corresponding led indicates when this happens. Settings just below
where the led lights up will give you the cleanest/loudest effect signal with the least
amount of noise. Higher settings will make the repeats more compressed, overdriven
and fuzzy, with added harmonic content.
NOTE!: Although the Replicator can handle very loud input signals, the recording
head will saturate sooner, the louder the input signal is. If the optimal dry/effect-signal ratio cannot be obtained, turn down the input signal to the pedal.
Delay level: This controls the level of the delay(s). At the maximum setting, the delays
will have appr. the same level as the dry signal (depending on the setting of the Saturation knob).
Feedback: This controls the amount of repetitions of the delay. When set to minimum only the first delay will be heard. At high settings, the Replicator´s repeats will
self-oscillate. This control is bypassed if an expression pedal is used for controlling the
feedback.
NOTE!: Self-oscillation will occur at different settings, depending on how fast the tape
is running and which “heads”-mode is selected.
Delay time: This controls the speed of the motor, and thereby the delay time. Depending on which playback head(s) is chosen, the max/min delay time available is:
Head1: 250 - 1200ms
Head2: 125 - 600ms
This control is bypassed if an expression pedal is used for controlling the delay time.
FOOTSWITCHES
On/off: This switch bypasses the effect, using a relay in a true bypass config. This
means that when the pedal is off, the incoming signal is routed straight to the output
jack.
