i need help im planning to buy a hartke head, and i need to decide between the 3000 and the 3500. im playing in a basement band, but were warming up to smaller clubs and outdoor venues. would i need the extra watts that the 3500 puts out? also, is the graphic eq that much better than the rotary knobs? i currently play through a 120w Crate combo, and the limit light stays constantly on, and i get a bit of unwanted overdrive. my money is a bit tight. also im am buying an avatar 115 8ohm bottom cab followed by a 210. what should i buy?
