Re: [PolySix] Polysix Overdrive Mod

2015-11-30 by eidorian@aladan.net

This isn't specific to the PolySix, but here are some guitar FX
electronics sites that you might get some ideas from:

One very simple thing to try is to reduce one of the supply voltages
(or add a DC offset to the input, which should be very nearly
equivalent) on the voice summing op-amp stage, to give you
(voltage-controllable) asymmetrical clipping, similar to the Moog CP3
module (which is quite a nice, musical effect in small amounts). Then
again, it still probably isn't quite what you're looking for.


Alternatively you could grab a cheap guitar pedal from craiglist :) I
have a box of them that I love trying out on my synths! 

Cheers,
A.

were too clean. I needed a little more compression and more grit. So, I
started to look into modifying the Polysix to give me some overdrive or
distortion.

next attempt will be to add an overdrive capability to one of the
LM13600 OTAs. We'll see if that sounds any better.
