Okay so I run a Ampeg BA115HP combo at rehearsal. I run through a compressor and have punchy high-in-the-mids setting which I set via the equalizer on my Bongo bass. The amp has a regular and a -15 db input for "hot" outputs which the Bongo certainly is. I set the amp (gain, eq, and master volume) knobs at about 7 and run the bass through the regular input (as opposed to the -15 db). This gives me the volume I need to sit in the mix. Am I damaging my amp? I do not hear much, if any clipping, perhaps just a bit right at the early attack of the note. If I eq in more lows I certainly get some clipping. Does everyone else need to turn down? Of course I know this is an option for rehearsal, but what about live?
