Issue with Music Man Big Al Preamp
I've just got (yesterday) my EBMM Big Al SSS after a long time dreaming about it. It was an awesome deal in a famous retail store nearby. It was pre owned but definitely new. It played awesome, I'm in love with its tone, versatility and playability. However there is an issue that is blowing my mind. I gigged yesterday with it + an EBS Compressor and a Markbass combo amp. They've always worked fine. Most of the gig it was ok, but in the end it started clipping the hell out of my cabinet and - while clipping - it would stop sounding (something like a 300msec lack of sound). Later on it started "screaming" a permanent Mid high buzz (around 2Khz). I was upset and had to turn it to passive mode, so it worked fine till the end of the gig (on passive). But whenever switching the preamp on the buzz would start.
Today I did the very same configuration at home and played for an hour. The sound was perfect and nothing happened even if I crank it up as loud as it was at the gig.
Does anybody have an idea of what it should be? I don't wanna return the bass since I loved it, however I don't wanna lose money either.
