You might want to look at the Global Amp Gain control... If you want to use the same presets with hotter pickups, that can be a simpler option.I'm a passive pickup user that does lots of heavy palm muting. I just got a guitar with EMG's and when I palm mute it sounds konky like I'm palm muting a harmonic. Could this be a firmware issue or an active pickup issue? I've never got on with active but thought I'd give it a try.
