Hey, i need a bit of technical advice, not very knowledgeable in the bass amp area.
Ive recently bought a Behringer BXL 1800 ultrabass and took it to a live rehersal on sunday, it was bloody awful! I had nothing but issues, the gain/OD control which i had been using at home and set up perfectly, lost its nice sound completely, just like it was a normal channel, so we tried mic-ing the amp up, still no decent od/gain, then i added my boss bass overdrive pedal to the mix but randomly started getting awful feedback/humming noise, what started off quietly but got so loud i had to switch the amp off....so, then we tried using the DI output straight to the mixer, same thing (the mic was moved away from the amp and switched off....obviously!) but still the noise kept randomly happening, which then resulted in me disconnecting my OD pedal and having a really naff sound....but i dont know what else to do.....slightly concerned as i have a gig in just over 2 weeks :-//. no other instruments i.e guitars/mics were near my amp, and the volume wasnt very loud at all, if it had been i probably would have broke some windows >.<
any advice would be greatly appreciated!!
thankies,
