Looking to pick something up to mod to an expression pedal for the incoming Axe. My only stipulation is that the gears that turn the pot need to be intact. For references, I got a bunch of iTrader at ss.org, 21 positive (100%) feedback at eGay.
Shipping is to Canada.
Check out the BOSS FV-300L. I've got one and it's pretty great. There's one on eBay right now:

And if you don't mind a bit of DIY, you can buy empty wah pedal shells from Small Bear Electronics and put in your own pot and electronics.

Note that the kits come with the rack gear, but you have to buy a separate pinion gear for the pot. (or a pot with a pinion gear attached already)
