Adding soft clipping to a Klone?

[standingzero]

Hey all,
I'm trying to add a Soft-Clipping mod in my Refractor Klone, but don't know how to wire it on to the PCB. Could you help me figure this out?

I've attached a photo of the PCB and what I think is the relevant part of the schematic. For reference, here's the post that shows the soft clipping mod:

I would leave R-12 off of the main PCB and run jumper wires from it's spot to a toggle switch. Use a DPDT on/off/on toggle and connect the jumpers to the center lugs.  Also connect the 422K resistor (R-12) across those lugs as well. Then put your two pairs of clipping diodes on the top and bottom pairs of lugs. The 422K resistor will always be in the circuit just like normal. With the toggle in the up or down position you'll be adding either pair of soft clipping diodes. In the center/off position the soft clipping diodes will be out of the circuit and it'll be just like stock.

Awesome!!! That's what I was thinking. Thanks so much
