I have the Zoom B3N, but I thought I'd give this a go. I'm reasonably satisfied with my B3N, but this had a couple features I wanted. I like that it has PC USB audio/recording connectivity and a 1/8" headphone jack. The latter seems silly, but I am always losing my adapters, and the Zoom B3N makes you double up your headphone input in a 1/4" output jack. Boo. Anyway, the unit arrived today. Nice little high-quality box. The presets sound pretty good. Slightly less gimicky than the Zoom B3N's, but that's not saying much. My initial assessment is that the Boss is appreciably more complicated to program than the Zoom - even with the "easy" feature. The computer/USB programming probably mitgates this. I'm generally ok with the crazy light action the Boss unit has going there. But here's the kicker. NO POWER SWITCH? This seems like a really lame place to go cheap, and it's impetus to box this up and send it back. Connect your bass. The INPUT jack doubles as the power switch. Power to the unit is turned on when you plug into the INPUT jack; the power is turned off when the cable is unplugged What do you all think?
