Vox V830 Distortion Booster Clipping?

sevenisthenumber · January 06, 2009, 05:38:24 PM

I want to just do a simple diode clipping switch on this pedal but there are two sets of diodes on the board (d1+d3)(d2+d4). D2 and D4 are coming right off the middle two legs of the jrc488p (47pf cap in between diodes and ic).
D1 and D3 are going to ground after a resistor on the other side of the board.

Just curious what diodes effect the clipping so I can try some different ones out.

Any help is much appreciated.

There is a 830-schem on the web, can be found via google or other machines. The 1st stage has a TS-Style clipper, the following stage a classic hardclipper.

If my very nominal German has not failed me, somebody there reversed one, but you need to be registered to download it, and I'm headed to work. Maybe later. Anybody else have rights over there?

Nope, that's the V810, which is pretty much a straight up tubescreamer clone with mechanical true bypass.
