Markbass SD800 Cutting out
Last night at practice my Markbass SD800 kept Cutting out for a second or so at a time. I was using only one cab a Markbass 410. I hooked up a Harke head that was at the studio and the everything was fine, so I'm ruling out a problem with the cab. I bought the head in '08 and I'm prob out of warranty. Any suggestions as to what might be wrong?
