I'm looking for a small, compact multi-effects unit to add on to my pedal board for my effects loop. I have a Pod X3 live and love the sounds on it, but would like something smaller that can fit more conveniently on a medium to large sized pedal board. I'm not looking for a modeling unit. It doesn't have to have amp or cab emulators. I just want good sounding time and modulation effects, such as reverbs, delay, chorus, rotary emulators, etc... And I need it to be programmable, so that I can quickly switch to different effect presets. Technical difficulty level is not an issue. I'm a pretty tech savvy guy, so I can figure out about anything.

Any suggestions and/or advice would be greatly appreciated!
