Thanks for all the replies... got some research to do now.
Mark -- I was thinking around $200 for maybe chorus and flange.
...Although I'm really diggin' octaver, and some wahs... I don't think I can budget for the Boss GT-10B at this time, as I just dropped a load on a new RH450 w/cabs, and a new Dingwall bass.
Maybe I can find some of these recommended, 'used'. I'll keep a look out
[edit - just watched a few youtube vids on the MXR M288 Bass Octave Deluxe ... I'm pretty sure I gotta have one now!
...also checked out several GT-10B vids, and it seems to appeal more to the "hey, look at the cool space movie sounds I can make with this gadget" crowd. For some reason it reminds me of an xbox. I was really looking for someone to do an in depth demo of the standard effects... oh well.. I'm leaning to the single pedals anyways]
