Having completed my synth setup, I'm now going back towards the guitar world. But I needed two things: silent recording and preset storage. The A/DA MP-1 was at the top of my list, and after missing out on one deal and then having another deal fall through, I made an offer on one in a lot with a Microcab, both in excellent shape from the original owner. In the meantime, a Marshall JMP-1 popped up, and sold from under me right afterwards, for quite a bit less. But I'm glad I went with the MP-1, because the JMP-1 had a "JCM900" character that wasn't doing it for me. A Quadraverb as would be era correct, and a Yamaha MEP4 so I can use my organ-style pedals to switch patches complete the rack.
While I wish I had an Ampulator to get the power amp response, or that my Microcab was a Monstercab* so I could use a real power amp into it, I'm overall happy with the sound for now. And going from a chorused clean with echo to a dry chugging rhythm just makes me feel more powerful.
I just now found an MC-1 with the 7 pin cable on eBay just as they were running a Bonus Bucks promotion, so the MEP4 will be out. More room for a power amp in the future.
*and it's too bad I'll have to ship to Europe since the mod is not sold as a kit.
