[Help] Recently purchased a JCM2000......

Now ive got an offer to trade it +~$200 for a mesa triple rectifier. Everything I've seen from mesas online are amazing, the low end thump and high gain from them is one thing I've been trying to replicate with this amp. What do you guys think? I play alot of metal, from sabbath, megadeth and slayer all the way to mastodon and more modern bands. I've thrown a green mile pedal before the jcm and it sounds nice, but this still seems like to good a deal to pass up. The mesa's in near mint condition, with around 150hours on the tubes and a little rust on the transformer.

EDIT: Its a DSL from 2000
