CultureJam Triton Delay

Here's nice delay from CultureJam. It's based on the Rebote 2.5 delay and has a lot in common with many other PT2399 delays. However...

The Triton, diverges from the base concept by adding a second Delay Time potentiometer and a unique (in the DIY world) modulation effect. The Delay pots are selectable via footswitch (latching), and when switching from one time setting to the other, the delay time change happens slowly, just as if you were manually turning the delay time pot on a standard delay pedal. This causes a gradual pitch bend that slowly resolves to unison if a note or chord is struck and held when toggling between Delay pots. To control the speed of the pitch bend/resolve, there is a pot labelled “Slow”. Making the transition speed slower also makes overall delay time longer.

This is version 3.1 of the Triton, and includes all controls externally (the original PCB by Pickdropper had the Tone pot as a trimmer). Here's the schematic for reference, and the demo below is of an older version, but you get the idea.





In case it's not clear in the layout, the Time Switch is the 2nd footswitch.

  1. the regen control can get to self ocilation or infinite repeats?

    1. My guess would be yes, but I honestly don't know and can't remember if CultureJam mentioned that in his original build doc.

  3. not working. :( The signal is passing through the circuit but no effect.

    1. It happens to me when I forgot to put the transistor. Mine is working great.

  4. It's verified. Love this delay. It works great with other pedals.

  6. In my construction the delay repeats only once. Regen has no effect.

    1. Check the regen pot with an audio probe

    2. Or multimeter? I can only think that you would get just 1 repeat if the delay is not feeding back into itself at all. If im correct in assuming that the regen knob is just a volume pot which is routed back into the delay. test the resistance between soem stuff to see if it works, look at the schematic
