Hey, I've currently got a Randall RX120R and just not satisfied with its sound or size. It's huge, way to loud for what I'm using it for, and quite frankly just doesn't sound to good, so I was wondering if I could get some suggestions on a new amp. I mostly play in my bedroom, but I do play with a drummer on occasion. I play a range of music, Metallica, Eric Clapton, Lamb of God, Machine Head, Sublime, Van Halen, Pantera, Megadeth. I wouldn't want to spend more than about 500USD. This will be used almost exclusively with my LTD EC-1000 deluxe. Any help is much appreciated.
I hear line 6 spiders are good.

Only kidding. What country are you in and are you willing to go used?

Seeing as you seem to want a pretty versatile amp (don't we all), I'd say a Peavey Vypyr. The line has many amps, so choose whichever suits your needs of volume the best. The 6505+ 112 is great, but unfortunately, I find it to be quite the one trick pony. The trick is pretty damn good, though.
