I've pretty much been a solid state amp guy when it comes to jazz guitar. When I play I like a clean, warm sound. I'm definitely satisfied with my solid state but lately I'm thinking that some tubes might be nice for fattening things up a bit! I'd like to go vintage. The two brands that come to mind are Fender and Ampeg. I'm not an expert on the various Fender models, but I've seen certain blackface heads go for around $600. The Ampeg combos on the other hand seem to be a bit more than that. I guess it's because you're getting the whole package with a combo. So what do you think? I'd also love to hear which models of each brand you guys think would sound best.
