Yep, I would also recommend that. That's where I got mine, in fact.

Nice slider wah, Pedro. The toothless wah looks a lot like the Colorsound wah method.

yep, thanks lots,DIY-Wah2 is very useful

Yeah! But I didn't know it at the time I made the drawing.
Does Colorsound's really use all of the pot rotation?
Mine theoretically does, I already made a prototype of
it but it's still too flimsy to put on a real pedal.
Does anyone want to gather all of this ideas in a single page?
I've seen lot's of diferent ways to make a wah, comercial or
not. It would be cool.

Hi Pedro,

I've seen the idea in

http://www.geocities.com/stompboxworktop/rocker3.jpg

used in commercial pedals, the "Sound" wha+distortion and a volume pedal for organs (both made in Brazil). The "Sound" wha doesn't feel good, too much travel and a bad tapper. A friend of mine calls it a _ah-_ah pedal, because with the pedal all the way up ("W" - the bass position) you couldn't hear much of the guitar The circuit was identical to a crybaby.

I'll post a picture at Imageshack.

I believe that it does, or nearly so. In the Colorsound Wah, it's more of a straight piece.

My colorsound uses a small portion of a 500k pots travel, quite small about 1/6th.
 This made it quite easy to attach a pedal driver from plastic parts like zipties and 'pen-tube' section to the pot, since just a little 'piece of pie' is all the rotation that's necessary...the driver system doesn't have to 'wrap around or pinion the potshaft.
 Even direct drive via flexible tube would do the trick.
 My other diy treadle cases are the sprung-string type, and this allows me to pedal drive any size pot.

Some brainstorming:

This is used in (old) hard disks and floppy drives:



If you sub the motor with a pot...

Another option could be use a strain gauge - you wouldn't need any "moving parts" just something you can bend (strain) with foot pressure:

The Palmer volume pedal:



An articulated arm with a slot, the pot slider fits in the slot.

The Sound wha:



A rigid wire "hooks" on a U-shape piece screwed to the pot shaft.

The fuzz part is similar to the "Mutantes" fuzz but they've managed to change it enough to make it really unuseable.

Now that's about as simple as it gets! I wonder how smooth the operation of that is, though...
