My old singer swears by peavy mics, he had this one ($110) and loved the thing, compared to sm58 and his akg. I ll be the first to admit peavys not great, but they make some good stuff. i got a Envoy10, lil 35 watt combo $225, for that price and the quality, its not bad at all. good for writting songs by my self. I had a 5150 for like 2 days then returned it. But they make a 100 watt tube head(3 channel) that sounds good.
1 rule of peavy- dont buy used amps(combos)
One good thing is that peavy 4x12 cabs run 4,8,16 ohms, not all cabs run all 3. ( but, that doesnot justify the sound of the cab-to me it is lacking)
