Great, will have a read of that new.
I bought it as I was looking for a compressor a pedal and a subtle room reverb for bass, and realised that the Zoom was cheaper than two decent pedals. I have a few songs in sets requiring and octaver, and one with spring reverb/tremolo, and the Zoom seems to have that covered as well... so I sold my tuner, octaver, Boss FDR1 and a few other pedals, bought the B3 and I'm a good few quid up!
As much as I'm loving the Fliptop model, I didn't buy for the amp emulations, it's just that I haven't got round to plugging into my gigging set up yet (Orange OTB and SP212). I don't think I'll need the models for live work as I like the Orange.
For direct recording though, it's looking to be ace!
