XXL stompbox mod help please

[sonofspy]

Hi,

I have a Tech 21 XXL stompbox (1st version w/the chrome swirl top)
The distortion is just way over the top for my needs, so I thought I could
just increase the resistance on the gain circuit and make it more of a clean boost/overdrive.

The drive pot is a 100K Linear taper, Being poor and living in the stix like I do I added a SPDT
switch which allows me to add 130K resistor to the circuit (for a max of 230K).
This does decrease the volume a little (the box has tons of volume so that's not a problem)
and it cleans up the signal a bit, but not as much as I hoped (or expected)
So I think I am going about this in the wrong way to achieve my desired effect (no pun intended).

Here's the schematic.


Suggestions?
