We were playing tonite and man, way too much feedback! We play at a local rehearsal studio and the rooms are the size of an average small-ish bedroom. The PA and board are not ours so we really dont know how to operate them properly. Plus every week we seem to get a different room with a different board. The singer has a habit of moving the mic (i dont blame him) and often when he does... major feedback. Its a real issue as the guitar player couldnt have his mic loud for b/v's or else significant feedback would occur. It just gets really annoying after awhile. I know feedback occurs b/c of the proximity of the mics to the amps but being in a small room makes its really difficult. All i can say is thank goodness for earplugs! Any suggestions?
