This has been driving me crazy. My relatively new (2 years 2 months) Markbass mini amp and 102P cab were making an intermittent popping noise - just like a very loud clap - while playing gigs recently. It seems to happen when driving the amp a bit loud (but not crazy loud). At first I thought there was a problem with the amp, so I had it looked at by a Markbass authorized repair shop. Nothing wrong there. While playing a gig today with my backup GK amp (but same 102P cab), the clapping noise started again. I've played this cab with 2 different basses, 2 different speaker cables, and through both speaker inputs - with the same result. I'm left by process of elimination with the cab. As far as I can tell there is an electronic component where the speaker cables inputs attach. Could this board inside the cab be going bad? Does that happen? Thank you fellow bassist and tech wizards for any direction. John from DC
