I've run into a stalemate as to what amp I should get. I'll start by saying right now I play a hartke lh500 through an avatar b212. I like it a lot, but this is the only head I've ever had and I want to see what else is out there. I don't play in any bands yet, just occasional jams. But I like to play rock/90's alternative. Ratm, soundgarden, stp, toadies, nirvana and so on. So I've found 3 heads that have piqued my interest, all used. So, between an Ampeg pf500, Hartke ha5500, and Gk mb500 which would you choose and why? The hartke is my first instinct, basically because that's what I have, and Larry Hartke embodies everything a company should be. I appreciate any input, thanks. Edit: forgot to add, they are all gonna cost around $250 so price isn't a factor. Unless that price is considered too high or one is a better deal.
