Mickey Havn't ever used it - but I do have a soft spot for Zoom multifx. I think the bass versions of their multifx all sound pretty good. I'm a long time user of the B2 and when I have to upgrade (Eg. when my 2nd one dies), I'll get a B3/B1on.
I did suggest the multistomp cause it will do reverb and delay in one stomp box sized unit - with the bonus of being relatively cheap 2nd hand and you can store presets of delays/reverbs you've brewed up.
