I just bought a Boss Octave pedal - the OC-3. I use a Radial bassbone and put all my effects in the loop. I have a Boss CEB-3 and an MXR bass auto Q already. For the most part I only use the CEB-3 when I play my fretless and I only use the auto-q for the fretted. I will probably use the oc3 with both. I plan on using the octave and auto-q combined and sometimes the octave and chorus combined, but never (most likely) the auto-q, chorus, and octave combined. So... what order? Oh yeah, and I have a TU-2 as well, but I usually just run that from the tuner out on the bassbone. I do have a bassballs but hardly ever use it and I'm probably just going to leave it off the board as little use as it gets.
