Multi Stomp MS-60B : Flexible and very useful

I already have a Zoom B3, and had been rather tempted by this little unit. For my purposes, it's turned out to be very capable. I like Zoom's idea of not limiting the signal chain with these units, so you're not limited to a series of blocks each with a limited number of effects but instead you can put whatever you like wherever you like in the chain. I generally have chorus and an amp sim permanently on, and on some songs switch either an exciter or a pitch shifter in and out. It has a conveniently small footprint compared to the B3, although the B3 does gain on the flexibility front as you can switch any one of the three stompboxes on and off. You can also use a MIDI controller to change patches via the USB port, which is easier than bending down and twiddling the centre knob to do so. Sadly you can't edit the effects via the USB port, unlike the B3.
