Wow, thanks for all the feedback. Keep it coming... although I'm not sure if all the responses make it easier or harder to choose.
I'm thinking not so much on the spider ii anymore. The used one I'm borrowing is so darn heavy (around 35 lbs) and there's no sense in buying a new spider with all the other great brands out there.
Right now, I guess it's between the Vox AD30VT (thanks for helping me get over that grille
), the Roland Cube, and the Tech21 Trademark. Anything that could help me choose?
I'm kind of agonizing over the amp decision 'cause I plan on being with it for awhile. I'll go to Guitar Center soon and try to play on all of them, see what happens.
Oh, and I was wondering. How do you test/compare amps in Guitar Center? It seems like the tone is a bit hard to pick up when someone's wailing (very skillfully, though) behind you.
