Can you wire an expression pedal to an effect instead of a knob? I mean, can you wire the pedal to the knob wires and control the feature from the effect pedal?

Re: Question to the tech guys here about stomp-boxes (it might be a crazy idea)
Yes, two possibilities:
1. http://www.toneinprogress.com/
2. More difficult, but you can wire a stereo jack into where the pot is and use an expression pedal instead of the pot. If you only need two of the connections on the pot, I think you can have it automatically switch from the pot to the pedal when you plug it in. Otherwise you need to add a switch to select between them. Sorry, I don't have a schematic to show you how to do it... Also, the difficult portion might be finding an appropriate expression pedal resistance. I think 15K, 100K and 500K are common, but if the value in the guitar pedal is something different you might need to improvise.

I agree . . . a knob on an effect pedal is basically just a pot of a certain value. An expression pedal is just a pot that you can control with your foot, so you should be able to do what you want without too much difficulty if you're cannibalizing an old volume pedal.

Good point...
Can anyone reccomend an expression / volume pedal I can abuse?

The Morley one uses optocouplers though, doesn't it? The Ernie Ball volume, Boss Expression and Dunlop wah are all good candidates. What pedal are you wanting to do this to?

I want to buy a Voodoo Lab Microvibe. From all the sound samples I've heard I liked them most. I actually like their price more then anything :laugh2: but I also really liked the sound samples and reviews compared to others.
The only drawback in them is that is no foot control, and I like it on a pedal... it's a mean of expression for me in the same way that vibrating the fretting fingers or rocking the whammy bar in the end of a line is. I can use the wah on each song...
Vibe's are my current main pedal GAS. I wouldn't mind getting a flanger which I can control and get from nice and gentle color to the tone to crazy sounds in a song.

Re: Question to the tech guys here about stomp-boxes (it might be a crazy idea)
The only caveat I can think of is that, depending on where the pot to be pedal-controlled is located in the circuit, problems may arise due to the longer wires. You might get noise or oscillation but, then again, you might not.

I was thinking that he was just going to disable the standard knob and use the foot controller ONLY. Your way would be a little neater though . . .

I agree, looks like it is a dual pot, but two of the lugs are bussed together. The only expression pedal I know of with a dual ganged pot is the Chicago Iron Parachute and the Tychobrahe wah (parapedal?) it was cloned from. I wonder if there is a passive blend pedal out there?
Also, it looks like if you changed the switch to the standard 3PDT stomp there is room at the bottom for a jack. (But at this point the tone in progress thing might be easier/cheaper and more versatile, you can use it on the flanger eventually)

A long time ago, Electro Harmonix (I think) made a pedal for foot-controlling effects parameters. Instead of a pot, it had a short flexible cable that rotated as you moved the pedal. On the end, it had a set-screw fitting that replaced the knob on the pot. Wacky idea, but effective. Good luck finding one these days, though.
If you're going to experiement, get an Ernie Ball volume pedal. They're indestructible, have lots of room inside, and have a fuller sweep that a Dunlop (Vox/Crybaby) box.

There is a manufacturer who makes the first product you mentioned, I just have no idea what it is called. I don't think it is any of the big name builders though.

Re: Question to the tech guys here about stomp-boxes (it might be a crazy idea)
If I'll have a pedal to control the speed I'll have no need to control it by hand or switch back to the knob...
PFDarkside... do you have any experience with the Tone in Progress 3rd hand? the reviews I read about it were really bad (although it's a cool idea).
I might go for the volume pedal mod... can I remove the knob and just attach it from the knob hole?

Re: Question to the tech guys here about stomp-boxes (it might be a crazy idea)
I've done this very thing a couple of times. If you have an old Wah enclosure (Like a dunlop wah) it works brilliantly. I also did the other method using a stereo jack. The only limitation with the stereo jack is that, as mentioned above, you can only control knobs that are connected to 2 leads, OR 2 leads and a ground. I modified a tremolo so that I could control the speed of it and it worked perfectly.

How hard is it to do on your own? how much would a tech charge for it?
