Even though I'm happy with the B2-Four, I decided to get an MS-70CDR+ as well. At that price, it was kind of hard to pass up. The MS+ will be a bit easier to use, if I just pop some AA's in and use on short/casual gigs. I think I can deal with the way they've designed the buttons.
I see the MS-70... has a "mono synth" and "Z organ". Where the B2-Four instead has Z-Synth, Bass Synth, and BassTalk Synth.
Nothing wrong with adjusting to a product better suited for your needs. I'm in the same boat - I reverted back to my B1 Four after tiring of the rather large footprint of the B6. The B6 was wonderful, but some became too bulky for my tastes to be lugging to practices & gigs after some time with it. I thought I could get used to it, but alas...
The B2 Four will be a nice addition as the footprint is much better suited (for me), and will give me back the extra preamps, etc, that the B6 had in it.
