If you make it smaller in value, this will make high regen/res settings sound less metallic. If you want to experiment with more interesting high regeneration signals, solder in a wire bridge across R11 on the copper side of the PCB, turn up VR5 a bit higher (VR5 is normally set so that turning up the RES control all the way puts you just below the point of oscillation).ĭ) C7 sets the lower bandwidth point (bass rolloff) of the regeneration signal. If you shunt/short R11, the clipping of D3/D4 becomes "harder" and introduces more harmonic content. If you replaced R29 with a 22k fixed resistor, and a 100k pot, wired as a variable resistor (2 lugs, not all 3), you would be able to get everything from a *perfect* 50/50 balance to a much softer flanging effect, even with very high regen/res.Ĭ) R11, D3, and D4 form a soft limiter, to keep high regeneration/resonance signals from overloading the delay chip. If the value of R29 is increased, the balance is shifted in favour of clean. I would suggest a pair of 4.7uf caps, back to back, as a suitable replacement.ī) Maximum flanging effect needs a 50/50 balance between delay and clean signal, but sometimes you want just a taste of flanging. Faster speed can produce an effect that sounds very much like a ring modulator. If the capacitance value is reduced, the speed range goes higher. A) C27 and C28 make up a non-polarized 16.5uf capacitor which sets the speed range.
