I think that maybe im a dummy, but maybe it couldve been my cable/s. I hooked the head to my Mackie as a power amp and tested it like that, and it does fine….or maybe it doesnt like my 412 cab or something. Either way, I need new cables, and a power amp. I am thinking about the Carvin 1000 watt power amp, they said it would go well with my ’79 Peavey SP2s. Anyone know anything about Carvin stuff? I want loud!!!
