I’ve always found expression pedals to be tricky. The M-Audio EXP is fairly disposable, but at least they can be picked up for about $20 on eBay every so often.

I have a vintage EHX Volume Pedal that is super-rugged and beautiful, and strangely enough it works great as an expression pedal for the Holiest Grail and the Tube EQ; but it doesn’t work with the HOG. I’m trying to figure out if there’s a mod I need to do to get it to work. If that was possible, I’d say that would be the best expression pedal of all.

DiscoFreq has a pic of mine at his site, thanks to electro-melx, who gave it to me as a gift : http://filters.muziq.be/model/eh/volume

I know this is an old post, but I just wanted to say – I had the same problem. The little plastic nub that moves the potentiometer broke off after a single use.

After unsuccessfully trying to glue it back on, fruitlessly using the HOG without the pedal, and frustratingly looking for a new expression pedal that wouldn’t cost me ANOTHER hundred dollars, I actually tore open the M-Audio and fixed it myself.

I drilled a small hole into the pedal’s ‘arm’ and then inserted a small screw which takes the nub’s place. It was an easy fix, and now the pedal is 100% again.

I just thought someone out there might find this info useful.

Wow, muffmuff, that pedal looks tough..now I know which expression pedal to buy for the Holy Stain I am saving up for. Thanks.
…and somehow the pedal reminds me of….

P.S. ..and,yes, Fender&EHX4ever;, I read your post and fully agree.
