DELAY
X Type:
Build Level: Intermediate
Based On: madbeanpedals original
The Dragonfish is a compact, analog-voiced PT2399 delay with modulation. Whereas the two
existing Standard Series PT2399 delay projects (the Degenerator and Transponder) have dynamic-
based modulation, the Dragonfish has a full complement of LFO modulation with rate and depth
controls.
•
TIME: The delay range is around 50ms to 600ms.
•
RPT: Delay repeats from 1 to "infinity" or self-oscillation.
•
MIX: Delay signal volume.
•
RATE: Sets the speed of the delay modulation from a slow chorus effect (CCW) to a ridiculously
fast choppy one (CW)
•
DEPTH: The intensity of the modulation effect. Setting this CCW turns the modulation off
completely.

Point being, you can use the Dragonfish PCB to build a Rebote 2.5 with modulation by using the Rebote values where applicable. Both projects sound great, but a little different from one another.
