more extremes settings on the spakler?

[add4]

I just built the spakler for my guitar teacher and i feel he would like more fatness out of it. is there a way of making that happen?
i guess if i increase the value of the fat pot, i might get more of the processed signal ?
sounds right?

My first guess would be to increase the input cap. That should introduce more bass into the circuit. The next point I'm looking at is either C5 or C6. I'm thinking one of those (probably C5) creates a filter with the fat pot...
