I've had a bit of time to play around with the B3 today and it's pretty impressive, I own compressors, a pitch shifter, distortion, chorus and an octaver, most of which only get used at home on the fretless and I'll probably sell them all now except some of the compressors.
I find the B3 very easy to get on with and can see me having a few patches with amp simulation for practice/recording at home through the computer and a few more with out the amps for rehearsals.
I've never had a muti-effects unit before and the amount of sounds from this is amazing, great fun playing with the synth patches some track a lot better then others though and my sloppy playing can cause some odd glitches, one of the ptichshifters actually tracks better then any pedal I have owned, going down to an open E without glitches.
I'll probably use this instead of my Edirol interface even though it only does 16 bit 44.1KHz recording and you can't turn the displays off so they will be needlessly on while it's used as an interface only.
That's it for now.
