I'm looking for an octave pedal that will go up 1 octave and down 1. And one that will work for both guitar and bass. I don't need a POG. It's a lot of fun, but even the micro ones aren't really what I want. I'm not interested in a think like the Sub Up n wotever, a pedal which downloads plugs.

For those of you with octave pedals, what are you using?
