Sometimes a girl I know comes over to jam with my band . She has a great sounding voice but is really quiet. I usually set her up with either a 57 or 58 . but even with her channel maxed on the P.A. she doesn't seem ot cut through. What i was wondering was if I should get a Condenser ( small diahragm) for her to sing through would this help . Or would it pick up too much other stuff and cause problems ie: feedback etc. I plan on buying a condenser or two when i get my recording setup soon anyway.. what do ya think????
