I get asked this question pretty often so here it is:
Here are the settings (from 1 to 7):
LOW: 5
MID: 6.1
MID FREQ: 4
HIGH: 3
GAIN: 5
DISTORTION MODEL: 5
I plug it into my amp using OUT 2(MIXER). I have Marshall Valvestate AVT50 amp. So here are the settings of the amp (0-10):
BASS: 2
TREBLE: 8
(i don't have MIDDLE for the clean channel)
I hope you'll be able to get at least similar sound with those settings!
Enjoy it!
