I want to start doing medium sized gigs, and also recording stuff. I need something that will deliver good tone.. loudness is not as important since i could just mic the amp. My budget is basically under $600 US, so i've been considering Vox AD100VT, Fender Hot Rod Deluxe, Peavey Classic 30. I'll be playing with a Gibson SG, and it is really important that i have capabilities of going from Rush-esque tone(YYZ, La Villa Strangiato) to good cleans.

Any suggestions will help, especially if they're in the price range(< 600 USD)....

1. people will want to know what sound you're after, or who you like.

2. and Some others will say the same thing, Try out amps yourself, unless you happen to be deaf.
