I wouldn't say it's way more complicated than a MP-1, just a bit different as it's purely designed for bass and what bass players need. So you have the tube and SS stages in parallel (combine as it suits) and then a strait forward path to the 2 fx loops. Where it really starts to mess with your head is the CC stuff, not so much what you can do with it, but how to set it up. That did take some reading/thinking/drinking to get my head around. But I spose I've had a MP-2 for a long time now and I just found it (the MP-2) a great leap forward from what I had in the MP-1. The only bit of the MP-2 I've never played around with is the macros. I'll get to them eventually, but then I don't have a huge need to drive that, just curiosity...
Maybe do a quick recording before you send it to Belgium so you can compare the MDRT vs stock tranny. Peter of course will know this as he's been on that journey. Both of my MB-1s came all souped up
so I've never got to compare, not that I mind, they are just amazing, with, as you have discovered, great bottom end. Man, running in stereo (Alembic > MB-1 > mixer > TC MOne (lite delay/reverb) > B200s > Messa P112 cabs), melt me....
Just had a look at the Cort Jnr, looks like a nice bass
BTW I'd recommend a set of Alembic CX-3/45/S short scale strings for it, it's what my Alembic SC Brown came with. Love them. Hex core, finishing wrap is an oval. The shorter axis of this elliptical wrap faces the fingerboard. So less fretting hand noise as you slide up and down and easier on your fingers (without killing the tone like flat wounds do). And they are made (length) for 2 aside tuners. Alembic have a retail site on Yahoo, so easy to buy.
