Dunlop JC-95 Cantrell Signature Wah

From the source:

One of the most influential guitarists to come out of the Seattle rock scene, Jerry Cantrell's epic riffs and searing tone have been the driving force behind Alice in Chains since the late 80's. His melancholy wah-drenched melodies in modern classics like "Man in the Box" and "The Rooster" left an indelible mark on a generation of guitarists. Jerry favored wah-wahs with a wider, darker response, and Dunlop has painstakingly replicated that moody sound to create his signature pedal. It's custom-voiced for a tight, punchy heel-down tone and a rugged side-control knob lets you fine tune the toe-down frequency. And with its antique, oxidized "road worn" brass casting and custom Alice in Chains tread, this is one pedal that looks as great as it sounds.


  1. Isn't it essentially a standard Crybaby with two or three component swaps and the pot? I saw a Crybaby awhile back and did it It sounds awesome but maybe I'll have to build the whole thing over now.

    1. you're spot on jim. in all honesty nearly all crybaby and crybaby like wahs are essentially the same with some component value differences. this goes for the legendary vox wahs, colorsound, boomerang, etc. the thing is that it's a very tweakable circuit, and little changes make huge differences. so if you look at all the wahs i've posted recently they're all the same with component differences. i could just put up a generic layout and list values for different parts to make each one, but it's actually easier and quicker to modify the layout and make a new post.

      there are differences though in some of the newer wahs from morely, ebs, and a few others. i will say that the newer ones that are based on the Q535 crybaby circuit have additional features around the same overall 2 transistor wah circuit. the first stage is an input buffer, which was not found on the vintage ones. when i have time i plan on working on a layout for those wahs as well.

      personally i don't plan on buying a new wah again, and would much rather build one. i can tweak it to how i like, the build quality is better, and i use better components.

  2. Thanks for the confirmation on that Zach. The Cantrell wah is definitely worth building if anyone is considering it.

  3. Oh my God, great work Zach, thank you so much!

  4. Caught an error, there should be a cut next to the 10k to ground off of the emitter of q3. will update the layout shortly.
