I live mine. I had one a couple of years ago and moved it on after a while and replaced it with a B1-four. The B1-Four has loads of features that I’d never use (looper, drum machine), and has a more flexible interface, but I didn’t really notice a massive difference in the sound, and it had double the footprint of the MS60b.
I run mine in an fx loop with a blend, so I can take it out of the signal path when I’m not using it, which gives me time to scroll through to the next effect.
I use it live and it does what I need it to, but for studio work I use all analogue stuff - especially octave and chorus, just because I’m fussy about those sounds.
