hello! I'm a relatively new bassist that has kinda gotten in over his head. I started playing in a blues band and my guitarist has a loud ass tube amp, I have a peavy TNT 115s, which is an old 1x15 combo amp. I'm not quite able to match his level so he's talking about helping me out with a new set up, I just have no idea how amps and heads and cabs and ohms and watts and pretty much anything electronic about playing. I was just curious as to how, say, a cab of four tens would compare. thanks!
