In this video, Kirk Hammett discusses his signature Cry Baby Wah pedal:

“It was like a nitrous switch. You hit a nitrous switch in the car and then your car just takes off. That's what the wah pedal felt like from the very beginning for me, and I’ve always been way into it.

There was a time where I needed 8 different wah pedals because of the Black Album tour, we had the diamond stage, it wasn’t feasible for me to keep running to one side of the stage to play a particular solo. So we put different wah pedals everywhere, and what we did was we devised a system where the wah pedals would be just chassis, and the main guts of the wah pedal would be in a rack. We went to Dunlop, and they designed something for us along those lines, that led to me sitting down and developing this wah based on the settings that I used in the rack-mount. Which is great, I can pick up one of these and it’s there - it’s the sound.“

Bobby Cedro, a senior engineer at Dunlop then goes on to describe the specifics of this signature Wah:

“…this was actually really interesting project, difficult yet somewhat easy, too. My job was to take Kirk Hammett’s DCR1SR, which is this big rack, remote Crybaby, all of the settings, all of his parameters, all of his tweaks, and put it into one pedal. And I built a prototype, and I further had controls for him to tweak up - so as it was sent back to him he played it for a while, did a little more tweaking with the EQ and the Q. So when I got it back it was my benchmark, where I married all those parameters, inputted into this pedal.

So, all of those parameters make this pedal a very musical and even sounding pedal throughout its whole range. All that EQing does, is smooth out the response through its travel, making in Kirk’s case playing at loud volumes and distortions a very nice and even wah wah swell. So the low end doesn’t get too boomy, and the top end doesn’t get too shrill. And all the middle points too are very balanced between the top and bottom.

And that's what his fine adjustments did for him on stage, and now you simply get all his sounds, and all his years of experience, tonality, all in this one pedal.”

"My pedal board is pretty simple. Aside from the Ground Control Pro and volume pedal, I'm using the Kirk Hammett signature Wah from Dunlop. I actually don’t even own this pedal. It belongs to my other guitarist, Matt. Aside from its undesirable look, it gets the job done well."
