if your distortion's power supply is not noisy, and you still get noise, i'd guess it's any one of the following:
- you're pushing the gain too much
- your distortion is noisy itself
- something else
I tested with a x0xb0x who has audio grade electrolytic capacitor's, it's the same result than a x0xb0x with cheap capacitors.
heh, i think you misunderstood me
"audio grade capacitors" sounds a bit like audiophile stuff
what i meant was, if the power supply from which you power your distortion circuit, is noisy or unstable - you add capacitors and/or other elements to smooth it out
example: many of the capacitors on the IO board are not there to filter audio, they are used as reservoires and as smoothing, then also pretty much each section of the synth circuit also uses capacitors to filter or "decouple" itself from its power rails
check your distortion, check the actual noise
try feeding another audio signal into it, feed silence, short its input to ground (if that's safe) and see what happens with the noise in those tests
