Clipping switch? Mosfets as clipping diodes?

[Nightendday86]

So I'm working on the Chela OD,how would I use mosfets as clippers? I want to wire a switch between the regular clipping (red LED) to mosfets for a different, softer attack/clipping.

I'm just wondering how I would include something like that? Would I use jumpers on the board and then wires to the switch?

There’s a section on how to add clipping diode options to a big muff board. Similar idea to what you are trying to do.

Like this, could I have stock, and then 2 other options?

The links jimilee and I posted both do the same thing using slightly different wiring. They give you two options depending on what you connect to the outside poles.

You could get a third option if you use an on/off/on switch. When OFF, you would have no clipping diodes.
