Re: Fender Frontman DSP... tell me about them.
If you can get a super-champ XD and run it into a large cab I'd suggest that instead. The power tubes do smooth the tone out, but it somehow falls short of making it feel like a "real" tube amp. It'll do some deep, creamy, neck-pickup solo stuff, though. Maybe you can get a good cab with loud speakers for it. The thing is you can't footswitch the channels, so maybe it's not so giggable in that context, if that's what you need.
You maybe outta get something that gets glassy cleans and pink floyd sounds on it's own, without modeling, if you can help it. Just a good, channel switching Fender tube amp. They're just as versatile if you know how to use em, and they all sound better. The new Supersonic 112 comes to mind, or the original super sonic. You probably aren't looking to spend that much if you're looking at the FM series though. Cheaper than the SS, The hot Rod Deluxe isn't terrible, it's actually pretty good, but it's got more midrange than the blackface 'glassy clean'. The drive sounds a lil rough around the edges but it's a lot better than a solid state amp. Then there's the Hot Rod's relative the Deluxe VM. haven't played that one but it comes highly recommended.
Some other people will chime in soon about Vox modeling amps, if you have to stick with modeling. Those seem to be pretty popular.
