its well known now that this guy is the Josh Homme amp... I was into them before that. A neighbor had one of these he bought new and all the friends of his kids, myself included, enjoyed playing through it because with the active, semi parametric midrange it could cover a lot of ground with any guitar. This amp delivers a muscly 70s rock tone lean or turned up to mean, Its usually stock with CTS ceramic 10" speakers that have some of alnico CTS vibe of an early super reverb but more authority. It weighs a ton, more than any other 4x10 you'll encounter. These amps have a complicated circuit on multiple PCBs and can be very confusing to service even with a schematic. They also use some oddball tubes in the preamp. When I owned one there were no 6L6es that could hold up to the high voltages. The originals were designed for 7027A tubes. These days the JJ 6L6 will handle it no problem, but I used to eat tubes power tubes. All these factors made this a once-in-a-while amp for me back then. Eventually I left it at my buddy's as a gift (he loves the stones). Frankly I didn't want to lift it or deal with the retube it needed. I liked it, but not that much. My friend didn't keep it either. He traded it off. If you have a great tech, a source for NOS tubes and a guy to help you lift this (mine had casters, but they were no help getting in and out of a van) then this is a great American amp that can do a lot. Otherwise? skip. yes it will do all those queens tones with a tubescreamer and some cool fuzzes out front.
