Picked one of these up for next to now't a while ago and haven't got round to trying it out yet. My current live FX thingy is a Line 6 Pod XT Live, which works fine for what I want but it's frankly complete overkill given that I currently use only 4 effects/settings: octave, chorus, B-15 sim (for old-skool) and SVT sim (for grittier stuff). The XT does a good job of the sims, but the chorus isn't brilliant and the octave sucks TBH. My question is, are these four things available on the MS60-B, and are they good? Is its octave setting as good as an actual OC-2, for example? It'd be great if I could whittle my board down to just the Zoom, a volume pedal and a tuner, but should I consider using a separate octave pedal too? And will I need a degree in order to figure out how the Zoom works?
