Mine are a Fender Prosonic as my gigging amp and a little VHT Special 6 running through a Jensen C10r for a practice amp at home. Despite it being a "meh" little speaker, it's perfect for driving the VHT hard without it being too loud.
Fender '64 Custom Deluxe reverb...completely opposite to both my Marshalls (SV20H and 2525H), which is why I wanted it. Lovely rich cleans, plenty of headroom for the gigs I play at and sounds close enough to the memory of a Twin I played through once, but I can actually lift this one.
Bogner XTC 25 Watt. Not sure what's going on with the rollout for this amp. They were supposed to be available this past Spring, but only a few were built and shipped. I'm one of the lucky few who got one early.
I've got a number of Valco-made amps from the late 50s and early 60s; they're definitely capable of Marshall-like behavior!
I've also made a few amps inspired by Valco designs. My version of the Supro 1688TN features a few crucial circuit tweaks, a smaller cab (the original is a 2x12, mine is a 2x10). One of my all-time favorite amps.
My desert isle amp is a Satellite Barracuda - it will get put in the boat whilst the 6 Marshalls 1959, 1987, 2-JMP 2203, JMP 2204, 2555X will have to fend for themselves.
Two knob, KT66, no negative feedback swinging a big pair of sweaty Billy Gibbons balls. The harder decision would be which speaker cab would get to come. GBs and BBs are great but this is the first amp I've ever played that makes EVM12L's sing like angels - rock and !!$**!! roll angels, that is!
