DSL20HR weird thump in 20 watt mode
Hi everyone, I love my DSL20HR, but every time I put it in 20 watt mode, I get a weird thump that sounds like someone knocking on a door through the cab. I guess it's somewhere in the power amp, but I'm not sure. I got both amp and cab used. Anyway, hopefully someone has experienced this issue...- TCF805
