Mesa JP-2C. You can get smooth. glassy, compressed sustaining lead tones in channel 2 or 3; you can get full, rich, pristine or edge of breakup jazz / fusion cleans in channel 1.
I'm running a Fractal VP4 in 4CM; and usually only have a compressor or envelop filter in front; typically use chorus / modulation and delay in the loop. It's "my everything but classic/hard / psychedelic rock" amp which are my Marshalls.
That said, I normally use my Fender Super Twin with my D'Angelico Style B when I want cleans but the JP-2C is more conveniently located here, so I use it more than the Fender.
