A Marshall JTM45 and a couple 4x12 cabs with 25-watt celestions, a Vox AC30, a Fender Twin Reverb, and enough of those giant sound screens to avoid noise complaints from the neighbors.
Simply the holy grail overdrive amp. I love the lead tones I've heard from this thing and the rhythm crunch tones are out of control. I may realistically get one down the road to add to my Shiva.
Bogner 20th Anniversary Shiva (2.5k USD):
This is the best all arounder from clean to lead.
Matchless DC-30 (2.5k USD):
This is one of those holy grail clean amps, chime and depth for days. I dig the hell out of my Vox AC15HW, but I can't say I wouldn't like to own a Matchless at some point. Those things are indestructible.
I'm thinking a couple of White Marshall cabs to make a Stack with my 1959RR, a JTM45/100 reissue, an Engl Fireball, Bogner Uberschall (sp?), a Peavey Classic 50 and a Classic 30 anda G System or similar Midi control system.
