I have a Goodsell Super 7....I was using it today on 7 watt mode with a HBE Power Screamer and a Creation Audio Labs 4.23 Pro....amp was cranked...guitar on 10...and HBE and CAL set moderate. I was digging in on the guitar and the amp cut out and made a real harsh noise a couple of times. What is this all about? Did I almost blow up my amp? Any ideas?
