MXR ZW-44 Berzerker Overdrive
Got a request for Zakk Wylde’s signature overdrive from MXR. It’s essentially Boss SD-1 Super Overdrive without the buffers. Original units have MC33178P, but socket and experiment with dual op-amps. You can use right angle PCB pots to mount them on the board from the solder-side.
Little Angel Chorus
Here’s a simple, fairly low parts count chorus based around a PT2399, designed by Rick Holt (aka Frequency Central) from the DIYStompboxes forum. I’ve drawn 2 versions, one with board-mounted pots, and one off-board pots. The 2nd IC (NE5532 in the layout) can be any dual op-amp (a TL072 works well), just socket and experiment. … Read more
Dunlop GCB-95 Cry Baby
Here’s one of the most classic effects of all time, the Cry Baby wah-wah from Dunlop. The big red thing in the layout is the Fasel inductor, and there’s room on the board for a pull down resistor at the input if you need it, I just didn’t include it in the drawing. What else … Read more
Electro-Harmonix Big Muff π
I got a request for a layout of the Big Muff that could be used to build the Triangle, Rams Head, Green Russian, or NYC versions. While it shouldn’t be that hard to take one of my previous layouts of the BMP and make the value changes, I thought I’d make a more detailed project … Read more
Escobedo Punch-In-The-Face
Today’s #fuzzfriday offering is the Punch-In-The-Face, designed by Tim Escobedo. It’s based on the Fuzz Face, but with a JFET in Q2. Here’s what Tim had to say about it: The latest Fuzz Face inspired offering. The big difference is the “Trauma” control, when used with the Gain control, will yield tones from hard fuzz … Read more
Wampler Triple Wreck
The Triple Wreck is a high gain distortion that some say sounds like a 5150 amp. It has a 3-band EQ and a switch to select between “Vintage” and “Modern” tones. There’s also a built in boost section to take things over the top. I’ve laid out the distortion section and the boost section as … Read more
Montezuma Fuzz
Here’s another Dragonfly design. This one is basically two tweaked Electra Distortion circuits stacked back to back. Here’s a sound sample. Should fit pretty easily in a 1590a.
Dunlop Fuzz Face – Eric Johnson
Here’s a layout for the Eric Johnson Fuzz Face. Had someone ask if they could build it on the basic Fuzz Face layout from last year. Since there’s a few extra components in the EJ version, I thought I’d make a specific layout for it. Should still fit in a 1590a though. Q1 is a … Read more
