I have a Fender PT-100 pedal that I was using w/my guitar setup (yeah, I play guitar too). It seems to be working pretty well with bass so I'm planning on putting on my pedalboard that I just ordered yesterday. The pedal has two outs; output 2 mutes when tuning, so that takes care of "tuning noise." I'll keep my eye on the FS forum for good deals on used Korgs.
