I just wanted to share a problem I'm having and to get opions on what to do about it. I am trying to record a quartet including trumpet, piano, bass and drums with a zoom H4. Because the mics are fixed on the recorder, I put the recorder about 5 feet in front and off to the side of the trumpet, at about chest high level. But even though I have the bass turned up the recorder doesn't pick up the bass very well. I haven't tried this yet, but what if I put the mic closer to the bass amp? My only problem with this in theory is that then I won't pick up the other instruments very well. Does anyone have any suggestions to even out the recording levels between the instruments, short of using more microphones and a mixer?
