As mentioned in a different thread, are you specifically wanting a digital modeling amp, or an analog amp?
I've been a HUGE fan of the old Randall RG series amps for years, and I own an RG-80 (80w, 1x12 combo) and it's big brother RG-100? (100w, 4x10 combo). These are from approximately 1980.
These are the amps that Dimebag Darrell used for his heavy crunch tone, but that's not what I use them for. The overdrive sound more like a Warren Haynes or Billy Gibbons tone to me. But they have a glorious and huge clean tone with more headroom than you can imagine. The punch that they have is amazing. And if you've ever played a Voodoo Lab Sparkle Drive pedal, which has the ability to blend clean and overdrive tones... the RG series do this with the two channels. You can blend the two channels, and even engage that via the footswitch.
The coolest thing? I got the RG-80 for $90 (in 2001). And I got the RG-100 for $120 (in 2010).
To be sure, I still use my old Alamo tube amp a lot. But I also use my Randall amps a lot. These things can be found sleeping away in pawn shops across America, and many of them come stock with original Celestion speakers (mine did). I've got an original G12-80 in my RG-80.
If you ever see one, check it out.
