More Gain/Saturation for Guv'nor?

[bluefireamps]

I've built and tweaked a GGG Guv'nor pedal. It sounds great, but I was wondering if anyone had an idea of how to get a little more gain and saturation from the pedal. Any ideas appreciated. Thanks!

Decreasing the 2k2 or 10k resistor, or increasing the 680k resistor would all increase gain, although they all might require capacitor tweaks to avoid changing frequency response. Google inverting op amp and non-inverting op amp to see the math.

You can also make the gain pot a bigger value or replace the LEDs with diodes, both of those will give more distortion.

Thanks! I'll give all that a go.
