From the list, I have owned a bunch of Carvin gear: an oak X guitar amp I got in 1981, an LB20 bass in 2000, a headphone amp I'm using now, and two stereo power amps (one from 1981 that I sold, and a DCM1000 that's in my rack). The X amp was vastly improved with a Torres Tone Kit, and was relatively trouble-free for the 26 years I owned it. It was traded away last year toward
a Korg D888, since I don't like hauling heavy gear around any more. The bass was traded toward a Fender Classic 50s P, which is my main gigging axe: I couldn't get along with the 24-fret neck on the Carvin. Both power amps NEVER needed repair or even a tuneup. Reliable stuff.
I have a Behringer Ultra-Curve Pro that I got when they were closing out the first generation models, but it's mostly to entertain visitors to the studio.
I have had 2 pairs of Peavey speakers, due to low cost. I have nothing against Peavey quality, but their design philosophy is at odds with my taste. They like lots of features: I like simplicity (and, hopefully, enhanced reliability). Having said that, it occurs to me that I ran a coffee house in these parts for a year using a borrowed three-legged Peavey powered mixer, beat to &^%$ and with maybe half its channels working, and it did fine. Ugly as homemade sin, but there it is.
