i would like to get some feed back on a crate 5112 50w tube amp. i found one for $459 used it seems to be in good condition. Also found a marshall tsl602 60w combo for $850 reg. is the marshall amp any good for that price? its listed at $1700. its a damaged idem but works fine. i want for play the usual stuff metallica to pink floyd. any info would be helpful. thought about using the tsl with my 4x12 cab. also would be nice as a portable.
