Alright, i play mainly progish and post hardcore stuff. Think Chiodos, The Fall of Troy, and Underoath. But i also do some clean and experimental stuff (an example of which is in my songies.) I play a Strat with Lace Sensor Hot Golds, which i know eventually needs to be replaced but its surprisingly hot so itll do for now. im looking preferably in the $400 - $600 range, so probably going for something used. I live in Dallas, TX, and will definitely be gigging.

Ive heard a lot about the Marshall JCM's, do yall think that would be a wise choice? or do you have any other suggestions? Thanks so much in advance.
Look for either a Marshall JCM2000 DSL50/100 or a JCM 900 SL-X if you want Marshall.
Also look at used Laney VH100r, great amps and ~$600ish used.

A Peavey JSX is also worth looking into
