So my friend, who is the main person I play with, is getting a 15w Tube Amp head (I think Vox) and a 4x10 cab. And I now have the money for a larger rig. I was originally thinking of a 200w head and 2x12 cab (GK stuff, MB200), but now I'm thinking of waiting a month and getting a 500w head with a 2x12 cab (MB500). And this friends tend to like to play really loud with bass very low................. Any thoughts???? Thanks in advance!!
