Since the MGMV isn't really a standard univibe for some reason I kind of wrote it off into some different category of modulation--have always loved it, but for whatever reason I never saw it as the end of my vibe search. But ya know what? Now that I've tried several other ones, every damn one I A/B with my SBMV I wind up coming back to the SBMV. The throb is just so beautiful, and on the 2 stomp the cupsize switch is just incredibly useful.
I'm still waiting to try a FoxRox Aquavibe, and if I can ever get my hands on an old Perscription Electronics Ultravibe i'll probably check that out too, but I no longer have any expectations of anything "beating" the SBMV for the sound I want.
As Robapov said, the EQ that pedal brings is one of its best features, slightly scooped mids, fat, round and yet tight bottom with a nice chiming top, mmm. I owned a SBEQ and PGC the entire time I had my MGMV and could never manage to mimic the MGMV's EQ, even with those pedals. The modulation ain't half bad either!
