Hey does 0 treble make sense, on channel 2? I turned the treble off, on channel 2, and it sounds good. I'm 5 pulled on the gain and 3 on bass, 2 on mids and 2 on the presence(not pulled) I think I need to take some time off, my ears are ringing, like crazy. let me know if this can make sense. I'm starting to think something is wrong with the amp, to have so much treble with it off. Going nuts! Thanks
