What the title says, really. This is for an AFB, but any preset should work, right? I've found and messed around with a Michael Britt JCM800 preset that's not too shabby, but I'm very curious to test out some others. I'm running a Tumnus and a Screamer-type overdrive into it to make it break up (mostly by boosting the crap out of it - low gain, high output on both pedals). I'm rewiring my board this week and I want to experiment with putting the AFB last in the chain, running everything in front of it (including modulation, delay and reverb). Going for that classic setup, slamming the front of the "amp" with the pedalboard.
