Modded my Crybaby

[Newc]

On a whim I grabbed a few resistors and a couple of capacitors and some jumper leads and started poking around inside my Dunlop Wah. I finally woud up soldering a 16K resistor to the two resistors circled in blue here:



Here's what the wah sounds like without the mod:

And here it is with the mod:

Excuse the poor Dazed and Confused hack - I was sitting, and tired.


You can hear how the tippy-top high end is rolled off (around the 16kHz I'd guess ) and there's no clipping in the Modded clip like there is in the Unmodded. However, there's an overall volume drop of a couple of dB.

There's also another spot where sticking the resistor jacks up the output, overloading a clean channel quickly.
Connect the 33K to either component circled in red with the 16K resistor and get some old dirty farty fuzz

Nice. You and John (jgcable) should go into the wah modding business together.

Nah, there's enough fish in that pond already

Plus, I'm not enough of a bastard to charge $30 for a $0.10 resistor

John's right, Newc. It's not the resistor, it's the KNOWLEDGE of WHAT resistor to use and where to put it that is valuable. No bastardy in that.

I'd gladly pay for John's modded wahs if I needed another one. I've got one modded Crybaby with the vocal mod that makes it sound like a Vox, and I love it. I had another one that got a vocal mod and something else, and also a kick switch to turn it into a volume pedal... Pete owns that one now (at least I think he still does) and he said he loved it, too.

my latest GCB-95 is also modded. It has some super secret stuff going on and I have been using it regularly live for the past 4 years. I did try one of those Zack Wylde wahs and it was pretty darn good. I can get a stock crybaby to do just about anything.

Did another mod today - removed the .001 capacitor and wired it to one side of a 3-way mini-toggle, then wired a .020 cap to the other side, and connected the center of the switch where the cap was on the board. Now I can switch between the original cap and the Hendrix mod (granted that's supposed to be .022, but meh, what's .002 here and there?).

The pot has been set so it's fully on when the toe is down.

First part (Electric Funeral) is the .020, 2nd version is the original .001 cap.

Next section (Voodoo Chile) is the .001, 2nd version is the .020

Last section is that Lenny Kravitz track "I want to fly away" or whatever. Never really tried to learn the song, but I heard it a few times on the radio and those chords sound close enough for this purpose.
First part is the .020, 2nd version is the .001

Oddly, instead of the center position of the switch being both on at once, it's like the wah is fully open, but not as harsh as either one, and the pedal doesn't work.
