I guess that, if both expression pedal jacks are Control Voltage types [should say in each product’s manual], it’ll work.
However, if either or both is controlled resistance type, it’ll be a mess.
just want julian to confirm that…

however, either way, your A-B idea does work. or getting a stereo volume pedal. or getting two of the boss expression pedals and duct-taping the treadles [foot-lever-wah-thingies, in non pedal nerd terms] together.

with a Y-cable or similar setup, you wouldn’t have the same sweep response. It’d sum the voltage output and divide it and it’s basically just a mess . If you’re deadset on doing both with one exp pedal, use an A-B setup

or get a stereo volume pedal and use it as the exp pedal. no clue on what you’d want for the sweep potentiometer though.

buy an audio jack at radioshack or from the internet, move the washer/nut from that one to the graphic fuzz.

or bring the pedal to the hardware store with you to get the sizes/whatever; most places i’ve gone have been pretty handy with getting me the right size stuff if I bring in the actual project. if there is a plastic washer [or you want to add one] and don’t feel like finding the right size, try cutting your own from the lid of a can of coffee/nuts/oatmeal.

make sure it’s mono, title it “track1.wav”, make blank copies of it [so they’re the same length] for all the other tracks, and copy over the tempo into the tempo.txt file on the card, and yes.

man, enough pitchshifters in that last one? I count three, maybe four if that last blue one that’s cut off is a ps-2,3, or 6.
