I'm considering buying a budget head and need some advice. I'm looking at the Gallien-Krueger Backline 600 and the Ashdown MAG 300H. Both are 300 watts and cost $299 from MF. I've got an Avatar 15" cabinet and play a Fender Jazz. Anybody have any experience with these? I'm looking for something reliable (I have gigs coming up) and good tone. My preference for tone is more old-school, not hi-fi. Thanks!
