Chunk Chunk, switchable SLO mods, how?

[camsna]

So some good pals have recommended how to make the Chunk Chunk more SLOish. They recommended:

1 - Remove r15
2 - Remove c13
3 - Remove presence pot

I thought that it would be bitchin' to put these mods on a switch. I'm great with an iron, but crap with a circuit. What's a good way to go about this? I was thinking implementing a 3PDT toggle, but am not sure how I ought to wire it up.

Lil' help? THANKS!!!

if you look at the schematic those components just roll off high end before the output.  If you wanted to put that on a switch I believe you could just sever the ground connection from lug one of the prescence pot and that would effectively cut those components out of the circuit.  I'm no expert but that doesn't seem like it would make it sound more 'slo' like.
