I think with all the rage about micro heads these days I should give a little props to an old school "lead-sled" that I just picked up. I bought a GBE 750 and played with it for an hour or so today at lunch. Wham! I'm so impressed (although it's bigger and heavier than I am used to). My amp history goes like this: Ampeg BA115 (1 year), GK 1001RBII (1 year), GK MB2-500 (6 months), Genz-Benz Shuttle Max 12.0 (a year), back to a GK 1001 for the last few months. I currently play through a LDS 212/6/w tweeter, although I've almost always used 3-way cabs of some kind (Dr. Bass for about 2 years :/ ) Now, I'll be playing this at band practice this weekend but I can already tell that the floor was rumbling in my apartment at the same volume I usually practice at. Now I know what you all talk about when you say that headroom improves the tone and feel of the amp. This is not to deride micro amps, I love them! I want to pick up another MB-500 now for jams and stuff. And who can beat the price/watts/size/weight ratio on some of those? Who else has some big amps that they love? Especially younger guys like myself who are moving from mostly smaller/micro heads!
