I own a Fender Power Chorus which is a pretty great solid state amp. The clean channel is superb but as usual, the dirty channel leaves a lot to be desired. The EQ, contour, and presence controls give it quite a broad tonal range but it simply doesn't have enough distortion/drive.
Can I increase the gain by lowering R16 which looks like 13K? What should I lower it to?
What other simple modifications could I make to this circuit that might improve the wimpy distortion?
Here is the schematic. Channel 2 is the distortion channel.
Thanks for any suggestions.
