My BBM is about 9 months old now and hardly been gigged, so i can't pit it down to wear and tear. I replaced the battery inside the pedal (as the old one ran out) and plugged it in. No sound came out of it. No problem, I thought, the battery is faulty. I put in a different 9V battery. Sound came out, but I had to nudge it to get it. When I used it, there was either no sound, quiet sound, burbly sound or proper sound. I have put the pedal not working down to the battery replacement. I would love to know how to fix it, because I find the BBM useful and urgently need it fixed. Thanks for reading!
