From the source:
The Disaster Transport JR is an analog voiced digital delay with 625ms delay time with an all analog dry signal path and true bypass switching. It was designed as an anti-modern delay for those who appreciate a nice vintage tape echo with all it’s peculiarities. Its unique tone control doubles as a noise filter on longer delay settings and really helps the delay shine with a dirty signal. The mix control allows you to boost the effected signal to nearly 4x the original signal level and the repeats control goes from one signal repeat to near infinite repeats all the way through to self oscillation.
Controls
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, muddy and disappear 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 it’s darkest fully counter clockwise and brightens as you turn it clockwise. A good rule of thumb is to leave the tone control between off (fully counter clockwise) and noon at longer delay times. This will remove all the common noise from hyper-extending the circuit.
Time: From about 30ms fully counter clockwise to about 625ms fully clockwise.
Repeats: Sets the regeneration of the delay line. From one single repeat fully counter clockwise, 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 clock- wise.
Tails:
A version of this pedal was requested with tails, so I took a look at the Deep Blue Delay, which this is based off of, and made the same modifications. To have tails, you don't use a 3PDT switch and the usual stomp
switch wiring, you're going to use a DPDT switch with the input and output wires going
directly to the sockets. With tails the stomp here will cut new signal going into
the PT2399 and so when bypassed the output of the PT2399 will continue repeating with the last input it received and the repeats continue, and IC1 will then act as a buffered
bypass. You may want to to swap the 47K resistor at pin 7 of IC1
for a 50K trimmer so you can adjust the buffered bypass level so you can have to
perfect unity with your bypassed signal. Another alternative is that you
can add a second stomp to true bypass the whole thing which will give you the option to mechanically bypass the effect as usual, or simply bypass with tails when you want.
