The obvious choice for a Fender alternative is a Marshall. But being a single coil - Fender guy from the start, I've never been able to master the whole Humbucker - Marshall sound. When I finally broke from the Fender mold, I chose Ampeg. I have a 90s reissue Jet and a 65 Reverberocket, and they seem to add that tonal variety beyond the Fender spectrum. And having awesome tremelo and reverb doesn't hurt either!
