Ok.. I have a very poor knowledge on anything related to building up a rig but have been looking for a nice but cheap amp. The stuff that seems to get closer to what I expect are the next: I'm thinking of buying a Hartke 4000 Head which produces 400 watts at 4 ohms and 220 at 8 ohms.. AND.. a 4 x 10 cabinet (Hartke VX 410) which handles 400 watts at 8 ohms.. So my question is.. Does that head make that cab deliver as much power as it is meant to? If it doesn't, is that a disadvantage? should I get a different set up?? (Eg: more powerful head or two 2x10" cabs) Alsoi what would happen if I add another cab to the set up... Would the cabs work better? Any info and recommendations are welcomed by this ignorant human being..
