I just stumbled on Factory Preset 229, which is a Marshall Studio 20 in a variety of configs (jumped, normal, some FX, drive, etc.) and man that might be the best amp in this thing for me at this point. I've always liked their Marshalls best of all the big modelers (outside of the JVM) but the Studio 20 is so good I'm half-tempted to pick up a real one. Right in the wheelhouse of the tone I like, cleans up great with the guitar knob, Hendrix-y in the mid-gain, and can get full gnarly dimed. Just lovely.
