Dunlop Dunlop GBC-95 Modded Crybaby

For those that are just never satisfied by whats out there in the land of wahs I took the standard Dunlop GBC-95 Crybaby and added some features based on common mod points. So how's this supposed to work?

Voice Pot: Changes the voice of the the wah by changing the sharpness and making it more "vocal." The larger the value the more "vocal" the wah sounds.

Gain Pot: Really this controls the overall bass and gain of the wah. The lower the value the more growl and bass you'll get.

Sweep Switch (SW): This controls the sweep range of the wah. The larger the cap the more bass sweep you'll get. For instance the common value is 10nF, which i put on the board already, and the bass wah has a 68nF. Personally if I were making this I would start with the stock value and increase using values I liked up to the bass value, but hey, that's just me.

Sweep Pot: This will control the range of the week of the wah pot. No different then what you find on the Dimeback or Cantrell Wah.

R1: This will set the volume of the wah, the smaller the value the more volume you'll get. Typically it's 68k. So you can mess around with it and get as much or as little volume as you liked.

Dunlop DB-1 Dimebag Crybaby

The original Dimebag wah, not the newer one, which will take a while to get done cause the board is completely different and based on the newer Q535 crybaby.

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.

Dunlop ZW-45 Wylde Wah Crybaby

Figured while i was at it, since there are a few signature wahs that are the based on the same board with a few changes, why not just make post a few other layouts.

First up the ZW-45 Wylde Wah.

From the source:

Modern Cry Baby Master Zakk Wylde and Dunlop have joined forces to deliver the toughest, meanest wah pedal on the planet. Built from the ground up with great tone and rugged durability in mind, this pedal can stand up to the crushing stomp of metal's reigning king of lead guitar. The Wylde Wah features a heavy-duty raw-metal casing and road worthy components to withstand years of ass-kicking abuse. With guts that have been finely tuned to Zakk's specs, this wah is specially voiced to deliver an extra thick and cutting tone.

Dunlop JH-1 Hendrix Wah

I was asked if I could make a layout for the hendrix crybaby, so here she is. not a whole lot different from a regular crybaby. There are 2 additional caps, resistor change, and different value pot. You may be wondering what these changes do, and in short it moves the sweep range lower.

I have one, it was my first wah, which I got used for $30, and personally I like the lower sweep. I've also compared it with a few others I've built, Colorsound Fuzz Wah and aVox, and I feel there's a nice sweet spot with this one when playing single coils. I know there are those that aren't crazy about it, but hey not everyone has the same tastes.

Dunlop GCB-100 Bass Crybaby

Dunlop's classic Crybaby Wah that was modded for use with bass. Not much else to really say about it.

Jim Dunlop CryBaby GCB-95

While I've got the wah template loaded I may as well add this one too :o)
Again thanks to mmolteratx for the schematic.

Info about the original:
When people talk about wah-wah pedals, they’re talking about the Cry Baby Wahs. This is the one that created some of the most timeless sounds in rock. The pedal that would eventually become the Cry Baby was first created in 1966 by engineers at the Thomas Organ Company. This new and expressive effect was an instant hit with players like Jimi Hendrix and Eric Clapton, who have contributed to the Cry Baby Wah’s huge popularity to this day. While other effects have come and gone, the Cry Baby Wah just keeps getting better with age.

Dunlop JBF-3 Joe Bonamassa Fuzz Face

Request, and as it was a quicky I thought I may as well get it out of the way.  A tweaked positive ground Fuzz Face using Russian germanium transistors.  Being positive ground as usual I would suggest trying it with a negative voltage inverter to supply the -9V and allow you to use a 0V ground and allow you to daisy chain with all the rest of your pedals.  Note the required pin orientation and arrange them accordingly.

Info about the original:
Following in the footsteps of Fuzz Face masters Eric Johnson, David Gilmour, and Jimi Hendrix—Joe Bonamassa relies on his Fuzz Face to deliver his trademark searing leads. Tested and developed over several world tours, the JBF3 Joe Bonamassa Signature Fuzz Face is voiced specifically for Joe’s humbucker-driven tone, adding sustain and thickness for a rich, creamy fuzz. This pedal’s hand-wired circuitry is built around matched NOS Russian military germanium transistors for their characteristic warmth and growl. The JBF3 also features classic Omeg pots, housed in a polished copper finish that will patina over time. “I wanted this Fuzz Face to be a pedal that would instantly transform your tone,” Joe says. “It drives you to a different place as a player. Kick on the inspiration box!” Production of the Joe Bonamassa Signature Fuzz Face is limited to a single batch each year.

Dunlop - Eric Johnson Signature Fuzz Face EJF1

There is an ongoing discussion on FSB about this pedal, because we know that there are some hidden surface mount components underneath the board, and so this is based on a best guess by Marc Ahlfs after some experimentation he did on the circuit.

Info from Dunlop about the original:

No one cares more about tone than Eric Johnson, and his choice for getting sweet, singing lead tones is the Eric Johnson Signature Fuzz Face. EJ worked closely with Fuzz Face guru Jeorge Tripps to create his signature pedal. It is inspired by EJ’s prized personal Fuzz Faces and is built to his incredibly strict specifications, featuring hand-selected BC183 silicon transistors (for higher gain), custom repro ’68-’69 knobs, and a vintage-style hammertone finish. The result: a beautifully dynamic, expressive, and powerful pedal. “I first heard the Fuzz Face when I was about 12 and loved playing through it,” he says. “It’s the classic tone used by Jimi Hendrix, one of my greatest influences. No other pedal gets this type of sound. It’s the pinnacle of psychedelic fuzz.”

Dunlop Q-Zone QZ1

Based on Analogguru's schematic, I really don't know much about this other than it's supposed to be a cocked wah effect but it was a request and looks like something a bit different.  At least it's a bit of a detour from the usual dirt pedals! :o)

I couldn't find many demos out there either but here is one I found on Youtube:
