Just thought it would be neat if we could compare our amp settings. I plug into the normal input,my usual settings are volume:5 treble:5 bass:10, contour:normally 10 but this is usually the only knob I need to adjust depending on which bass I'm playing. Bassboost off. Sounds great on,but too boomy with the band playing. YMMV Thanks for your input, SUNN RULES.
