1) As far as watts go, is the difference in loudness? So a 75W will be more powerful and louder than the 60W tube amp?
2) My friend is trying to get me to buy a big enough amp to be played over drums. He knows that I just play by myself, and I have for years, but he says that just in case I SOMEDAY decide to jam with a friend on drums, I would need an amp that could be heard over them so I don't get drowned out. My question is, what size amp would you need for that. All he told me was at least a half stack (which Im not too sure what that means). But are these two Vypers powerful enough to be played in this way, or would I need to go bigger?
