Im such a fan of marhsall that i couldnt even consider a crate over the guvnor, however, used jcm 2000 or jcm 900 100 watters from guitar center will be about 650-850 cheaper than an jcm 800 and will sound much much much better the 200 and 900 heads are very gainy and provide massive brit wall of sound...I have owned the jcm 2000 and its jcm 800 (2203) channel is very beeffy and has got tremendous heavey metal thunder at high volume...did i say high make that crushing.....
If u can afford the marshall do get it to pass it up and not be able to get it later will be a missed opportunity.. further the resale/trade value of the marshall we will be considerably better than the crate.... but most important the tone is legend...........................
Tonnally speaking, the 800 master volume can be turned all the way up to give a plexi-esque tone which u may enjoy...
