Here’s how the controls work:

Mix: Sets the output level of the effected signal. This should 
be treated as a gain control/ master volume for the delay 
line. Unity is around noon and everything above noon will 
boost the delayed signal louder than the original. This is a 
gain control so, like any pedal with a lot of gain, a hint of 
noise and distortion at max setting is completely normal.

Tone: Most delay pedals are heavily filtered at the output 
to remove the clock noise and other unwanted hash that 
is common from extending the range of the delay time 
beyond the limit of the circuitry. This usually leaves the delay 
sounding dark and muddy, and disappears when hitting it 
with dirt. The Disaster Transport has done away with a lot 
of the heavy filtering and replaced it with a tone control 
which allows the user to choose their desired sound and 
results in more natural tape-like repeats. The tone control 
is at its darkest fully counterclockwise and brightens as you 
turn it clockwise. A good rule of thumb is to leave the tone 
control between off (fully counterclockwise) and noon at 
longer delay times. This will remove all the common noise 
from hyperextending the circuit.

Time: From about 30ms fully counterclockwise to about 
625ms fully clockwise.

Repeats: Sets the regeneration of the delay line. From one 
single repeat fully counterclockwise, subtle repeats around 
9 o’clock, strong naturally decaying repeats at noon, near 
infinite repeats around 2 o’clock and full on self oscillation 
fully clockwise.

Depth: Sets the depth of the modulation to the delay line. 
The modulation is true pitch-shifting vibrato, higher depth 
settings will give sea sick pitch bending, lower settings 
will yield a more natural chorus/leslie/tremolo setting 
depending on modulation rate and delay time. To achieve 
a more natural modulation, the depth should be reduced as 
the delay time is increased.

Rate: Sets the speed of the modulation. Goes from painfully 
slow to way-to-fast allowing several different modulation 
styles to reveal themselves.

Bypass: Turns the effect on/off.

Modulate: When activated, it emulates the decaying sound 
of a tape delay. This makes the Rate and Depth knobs affect 
that modulation as well. When the switch is turned off, the 
other four knobs are the only ones that affect the signal, and 
the delay sounds will repeat without decaying.

Power:  Use a standard 9 volt DC power supply with a 
2.1mm negative-center barrel (not included). We always 
recommend pedal-specific, transformer-isolated wall-wart 
power supplies or supplies with separate isolated outputs. 
Pedals will make extra noise if there is ripple or unclean 
power. Switching-type power supplies, daisy chains and 
non-pedal specific power supplies do not filter dirty power as 
well and let through unwanted noise. Do not run at higher 
voltages!
 Current draw is 35 mA.
