Hello! As my very first post, I am going to pick everyone's brains. Does anyone use just a Peavey TVX 115 as their one and only cabinet? I am tempted just because the price is so darn cheap. I seem to be able to pick it up easily enough in the store, so weight isn't an issue. Would putting casters on it change the sound that much? Any other pros/cons? Thanks in advance for any advice.
