Ok, since this is the DIY forum, how about some of you effects modders sharing some of your ideas about mods to Wah's. I'm specifically looking for mods to the Dunlop Crybaby std. model, like replacing the inductor with a Fasel and converting to a tru-bypass operation.
Any insight or links to sites with this info would be appreciated...
Thanks all.

Upper left technology of... links then one for wahs. Covers how they work, what does what, and a lot of other great stuff.
Hey i'm currently modding my crybaby too and you should really replace the 33k resistor by a 68k if you want a good improvement. I ordered a fasel inductor also...

I went the other way. My vox wah had a 68K input resistor, and I dropped it down to a 33K, AFTER I modded it for true bypass (which is an easy and essential wah mod for any crybaby or vox wah). After the bypass mod, there was a slight volume loss when the wah was engaged, so dropping the resistance on the input fixed that.

I modded mine to true bypass and installed a fultone pot. The pot really improved it, a lot. I also installed a power jack (mine is from the 80's and had no external power jack).
I got most of the info from Fulltone:

How does a Fasel inductor change the sound of a wah pedal? Are there different types? Who sells them?

The GEOFEX site talks about how the Fasel inductor does affect the sound. No clue who sells them, might be in the article.

Support our friends over at DIYstompboxes and buy a fasel inductor from them; they have both yellow and red versions:

I've heard that these are relatively easy mods, just a matter of knowing where to go to get the info and parts.
Thanks for the input everyone.

The best mod for a wah would be to have the treble sound on the UP/BACK/HEEL <---- (choose you particular terminology) position.
Why is it backwards, on ALL wah's ?:confused:

Why do you say that?

Because the first wah pedal I ever owned was a Royal Fuzz Wah and the treble sound was in the UP position, it just felt natural to lean back on the pedal and have the thing screamin'.
I miss that thing. :(

Here's a dumb question:
Does modding a Vox V847 Reissue to be true-bypass require any external modifications to the casing? Can one easily tell it has been modded from the outside?

Couldn't this be done by simply reversing two wires on the pot?

TB mod wont effect anything external unless you want to add a led.

Could be, I'll have to borrow a wah and experiment on it..
Good idea, thanks. :thu:

great ideas. I've had a crybaby for years and have always been less than satisfied with the wweeeeeeeeooooooooo tone. I am looking for something a little less pronounced.

What would I have to do to mod my wah pedal so that I could also use it as a volume pedal? It's a Snarling Dogs Super Bawl Fire Bawls wah.
I rarely use it, so I'd be ok with just making it into a volume pedal - can I do that by wiring the jacks to the pot? Can I toggle between vol/wah by using a switch that will engage the board?
Sorry if I'm being ignorant.

I replaced the pot & switch on my Crybaby this weekend & rewired it for true-bypass. Kind of rushed the job as the week-end was very full.
I used it at the Saturday night gig & it worked fine. I have to adjust the pot travel just a bit as its not quite in the "sweet spot".
Thanks for the links & info guys! :cool:

I know this thread is 2 years old, but, this site has the best mods i've ever seen; great pics and easy to understand, step-by-step instructions. http://homepage.ntlworld.com/s.castledine/greenfuz/wah.html
I modded my V847 w/ TB and replaced my scratchy pot, also "vocal mod" . I'm working on the "sweep mod", I need more treble. I don't know if the cap values are backwards or I am, but I exchanged .01uF for .022uF and got ridiculously more BASS.

You did it backwards :cop: You more than doubled the value of the cap. Try something around .005uf

that's what I thought; but I didn't know for sure, so I asked some clown, and he told me less is the other way. rrrggghhhh. Thanks, I will fix it.

Here is a thread (http://acapella.harmony-central.com/forums/showthread.php?t=1847081) from a few days ago that included a really nice drawing of the true bypass with LED wiring diagram.
