I've ordered a prototype PCB for the updated Romferd. The circuit is very similar to the original:
* TONE switch is replaced by a knob that sets the cut off frequency of a low pass filter. The filter resonance can be tuned by adjusting an internal trimpot.
* CYCLE switch is replaced by a knob that sets the delay time. As suggested in this thread the delay time is locked to step (4 steps). Minimum delay time remains the same as that's just how the PT2399 works.
* Added an expression jack for feedback adjustment. Haven't tested this yet.
* Top mounted jacks on an upright 1590BB (same size as before).
Hopefully the prototype works as intended and I'll be able to start production of a smaller batch in November.

New Reverb prototype was successful too, but still requires a lot of coding. Think you guys will enjoy this one.

Just DIY it. You can add expression control to any knob...right? Am I forgetting something?
