I have a peavy 112 transtube efx (witch im tradin in for the 212 as said elsewhere) I had it on the floor in my mom's room and it sounded okay, i figure the sound was fine since the guitar isn't the greatest. I moved it on top of a metal fileing cabinet to keep it out of the way, i noticed after doig so it sounded A LOT better. It was like the guitar fairy gave my amp a tune up, any explanations? By the way, when i get the 212, Is it a tube or solid state amp, I'm a little weak on amp type info, anyway to tell?
