I have a mild dilemma: when I play upright gigs, sometimes I have a hard time hearing myself (even amplified) among the noise of the other musicians. I came up with the brilliant idea of using a personal IEM system, so I did research and got a Behringer P2. I've now tried it on 2 gigs, one running direct from bass to P2 via ¼-inch and the other from bass to Zoom B3, then out of output 2 to P2. In both cases (and also electric at home with all volume 100%), it's simply not even close to being loud enough. If this is enough info, am I doing something wrong? Is XLR a whole different experience?
