I just read something about Gibson Lab series amps going for around $300-400 for a 100 watt 4X10 combo’s, they’re clean solid-state amps, but they dependable as hell, and BB King uses them. Some fender twins go for $700-800, although they’re clean unless you crank them to their full brain melting 100 watt capacity (Sex pistols used this technique to get the distortion on never mind the bolloks. And Roland JC 120’s are really loud 120 watt solid state amps that’ve been around for years, prices start at a little less than that of a twin. My dad says JC 120’s are some of the loudest amps ever built.
I realize these are all combos, but they should fit your requirements.
