Well, it's been a while, but I did make a small change in the Mercury. Being so used to the Fender scooped tones, the Ampeg M-12 with its midrange bump has been a slowly aquired taste for me; I found that it was really something I was always trying to dial out. I took it to my amp tech and we tried changing out different component values but that didn't do it for me. I left it with him and after looking over the schematics again, he decided to remove the bright cap. The amp still sounds like an M-12, still has lots of mid range, but the harshness of it is gone. Now I'm kind of embracing the sound; still a challenge, but there is something about it that I really like. I'm using this amp for quiet jazz gigs so have no reference with the amp turned up loud. It was a very simple 'mod' if it can even be called that, but I really feel that it sounds better. The Weber Alnico speaker is a nice addition as well. I'll get a sound clip or a video up in a week or so and post the link.
