I won a modded Brown Module in an EBay auction. The guy said that it was a Pete mod, except that he went back to a .0047 cap at C3 because he preferred a fuller bass response. I am wondering if I should switch back to the .0022 cap? I run a graphic EQ in the effects loop of my amp and I do have the bass slider set for a small boost. The module sounds great, but if I turn the bass all the way up with the gain maxed, the stock Celestions in my RM-100 start to fart out a little. I also have Plexi, SL+, and Ultra XL modules and I can turn the bass knob all the way up on those modules and also boost the bass on the graphic EQ under high gain conditions without this "farting out". My solution for the Brown is that I have to keep both the gain and bass down to 3:00 or lower or not use the EQ boost. I am assuming the .0022 cap would help with the farting out, but how would it effect my tone otherwise? I do prefer a full bass response.
