what do you guys think the best tube combo for metal/hardcore would be for around $500? i would be willing to put a pedal over the od channel to beef it up a little.
IDK if you can get a Peavey 6505 for that much, I think used ones go for slightly higher.. but if you can find one that cheap on ebay, then a 6505.

EDIT: A peavey 5150 is the same thing as a 6505, just an earlier model. Try searching for those as well.
