I'm in a band with a banjo player and it is difficult to hear the banjo over everything else. Using a pickup has proven better than using a mic. We have run the pickup into an guitar amp and also strait into the mackie mixer that we use for our PA. If we turn up the banjo volume loud enough for it to get heard the pickup starts to feedback uncontrolably in the amp or the PA everytime. I know that the banjo is a hard instrument to work with in a rock setting, what with drums and all but there has to be some way? Any tips or gear suggestions. I was thinking some sort of compressor maybe or specialised amplifier. I don't know? Any help would be great. Thanks!
