I'm pretty noobish with effects, so bear with me. So I'm in the market for a multi effects pedal and these two seem like good choices. I was wondering if there was a significant difference between the two in terms of sound quality, construction quality, or something else I'm missing. I'm getting a multi effects pedal to test out effects since I've never really had any (except my MXR M80 which I still have.) I think feature wise (correct me if I'm wrong) they both have storage for user presets for different effects (and chaining them in one preset?) Also, the Zoom has a USB connector which I think is for interfacing with your comp so you can record, but can you edit your presets with your comp too? (Are patches the same as presets?) I don't need it for the interface since I have a Lexicon Alpha, but if you can tweak the settings with your comp instead of on the pedal, I bet that adds ease of use. Effects, they seem to have similar types of effects (which don't really speak of the quality of them, but by shear quantity, Zoom has slightly more)but the Zoom has the amp models too, which would be cool to try out. The Zoom does come with an AC adapter and is $50 cheaper if I get the POP model, and the Boss doesn't come with the AC adapter, so I'd have to buy one for $25. So the million dollar question (actually, either $160 or $235 question), is the Boss worth the extra $75?
