The volume part of the pedal works just fine. However, I'm getting no Boo-Wah effect at all from the tone part of the pedal. Any suggestions? Is it time to replace the pot? Any suggestions as to which to use? I'd like to get the most drastic sounding tone change as possible. I was even thinking about removing the pot from an old Wah Wah pedal that I have and sticking that in there........WHADAYA' THINK?

It's more about the cap attached to the pot than the pot! .022 or .047 depending on value of pot

If you want it to get really dark you can go to a .1uf or higher. The higher the value the darker the sound

Make sure the string is not broken etc. It should do the BW thing fine... it's the same as a guitar tone control, like a .05uF IIRC.

Thanks Guys...Kind of an odd deal with this thing. There was no warning at all...Scratch noise, etc...One second it was working and the next it just stopped. I haven't had a second to take it apart yet so I guess it could be the cord. I'll give it a look this week. Hope it's minor.

I'm not quite sure, but what seems to be happening is that the cord is slipping. When I'm trying to get a faster kind of Boo-Wah effect, there's no tone change whatsoever. As a matter of fact, it seems to stay in a very muddy sounding position. However, when I slowly move the flange/paddle to the left and back to the right, I can change the tone? Could the cord have stretched? IDK.....Any advice? Anyone have a Dearmond (SP) they'd like to part with??????

| I don't mean to hijack this thread Robbie, but I have an old one of these that's not working properly too, so I'm thinking of replacing both pots. What values should I look for, and where's a good place to get them? Thanks in advance. |

The original were 250K audio taper pots, designed for for a Telecaster or other guitars at that time. I would replace them with 500K audio taper pots designed for volume pedal use. |

1. The cord should be a 'healthy' sized 'cotton'-type cord, as opposed to the synthetic narrow 'fishing'-type used in many of todays pedals.
2. Where the volume-cord ends pass thru a holes, they are 'knotted' to keep them secure from slipping thru.
3. The ends of the tone-cord are tied to the end of its tension spring.
4.The tone-cord passes one and one-half turns around the 'barrel' on the tone-pot shaft.
5.The volume-cord passes one and one-quarter turns around the 'barrel' on the volume-pot shaft.
6.The amount of pull required of the tension springs are minimal, barely separating their coils (provided the pulleys and pots turn freely on their own).
7.When properly strung, the volume-cord will pass through the 'loop' created by tone-cord.
8.There should be a single steel ball in the curved groove in the 'toe-area' between the 'foot-treadle' and the upper portion of the pedals main structure. This ball acts as a bearing for lateral movement of the forward (toe) part of the 'foot-treadle'.

There's a spring inline with the string... if the spring is un-sprung then your cord has stretched out.
If your spring is still pulling, you can do two things:
1.) Lube the pot shaft (careful not to overlube!)
2.) Put belt dressing on the string
You might also try replacing the string... they do wear out. In fact, I'd try that first... you can test the pot shaft's free-ness at the same time.

Well, once again the last thing I checked out should've been the first. It turns out that the set screws in the sleeve were not tightened and of course, the post was not turning. Glad it was something simple. I'll know what to look for next time. Live and learn....

Rob, belt dressing was sticky stuff we used to spray on slipping V-belts in cars, in the days before the broad serpentine belts of recent years.

Belt dressing is the sticky stuff you spray on fan belts to stop them squealing (for a while, anyway)... and yes, 3in1 would work for your pot shaft, although I prefer Singer sewing machine oil, 3in1 is pretty much crap AFA machine oil goes... the best is probably Hammond Generator oil, zero residue stuff. Glad you found your problem... make sure your pot's not banging the stops or it'll degrade pretty quickly... the ends of the travel should be just off the stops for best life.

Depends on if you want the belt to be quiet (silicone) or to grab better (belt dressing). Either way it doesn't last long in the automotive application... the best belt dressing I've seen had beeswax in it, and was very sticky.
