Ugh, so I'm looking to trade in that piece of crap MG250DX sitting in my room, because at the time, my ignorance on amplifiers was blaspheming at best, and so I thought, "Marshall, big, OMGAMAZING." Idiocy doesn't go a long way in the world of guitars.

So, I'm trading it to the store that I bought it from, and in order to get the best deal, apparently I have to trade it for a $600+ amplifier, otherwise it'll only be a "standard trade" or whatever. I bought the MG for $500, so I'm not quite understanding this "best deal" thing, but if I'm getting a more expensive amplifier by trading in a cheaper one, I'm not looking to complain.

Regardless, the price requirement kicked the Peavey Valveking series -- apparently he gets the 212 for cheaper than $600 -- out the window, and now I'm looking for some all-tube amplifiers within the $600-700 price range.

I dig Dream Theater, possibly a bit too much, as well as Metallica, Megadeth, Ozzy Osbourne (Rhoads years), and I'm basically looking for tones within the progressive metal/heavy metal style. I looked around on some websites (musiciansfriend, zzsounds, et cetera) and saw some decent-looking ones, but I have no experience with them, so I don't know what tones I could possibly pull from them, thus, I'm back to square one.

Any suggestions, my horde of fellow axe-slingers ?

Peavey Classic 30 is right at $600. I would sell your mg on craigslist get more for it, stores will only give you 25-30% of the new price for trades so they can make a profit off the resale. The store will make profit off you twice.

The Peavey 5150 II produces some solid heavy metal tones, and if you look around you can probably get one for $650-750. I found it produces more of an 80s metal tone, which is really nice...but if you crank the pre up to 5+, you'll get some insane distortion if you need it

You should also take a look at a Traynor YCV50 Blue. People say it is one of the best amps for the money.
