This layout is for the distortion side of the Box of Rock. The Boost side is just a SHO. I’ve laid this effect out for top mounted pots like in my other Zvex layouts and should fit vertically in a 1590B. Pots are 1.1 inches (28mm) apart. Board dimensions: 3.2 x 1 in. or 81.3 … Read more
The Zvex Super Hard On has become one of the sought after boost pedals today. Derived from the preamp section of a 60s recording console, the SHO uses negative feedback to control the gain (which is what gives it the crackle when adjusting the knob). It’s capable of being a clean boost and adding some … Read more
The Zvex Wooly Mammoth is a Fuzz Face derivative designed for bass, but sounds awesome on guitar as well. For this one I’ve laid it out for on board pots oriented like the originals. On the PCB I added an LED and LED resistor for on/off indication. As with my layout for the Fuzz Factory, … Read more
Here’s my take on the ZVex Fuzz Factory. The originals have the pots mounted to the board as well, but ZVex uses the little square pots which are more expensive. I wanted a layout that used regular 16mm pots, which are easier to come by and what you probably already have in your parts stash. … Read more
I was cleaning up my layout folders and noticed that i had not posted this one up. It’s a slightly modified Machine. First of all, the second driver stage has a gain control now, per the Madbean “Macheen” schematic. Also, i found that using Si diodes and a smaller value for the Limit pot made … Read more
Don’t bother asking for a schematic. One doesn’t exist. This layout is based on FSB thread on the subject…. (yes, you’ll need to log in to see it) — The thread at FSB got wind under its wings after this layout, so the questionable values are finally confirmed. Here’s the final layout with updated values … Read more
Request. The vero version of this that I already posted included axial caps, this keeps the size down by using all radial caps and will be more handy for someone wanting to add a small boost board to another effect for instance. Includes details for adding a master volume pot. Geiri’s build of this layout … Read more
Vince on here asked me if I could adapt my layout to make a 2 Knob Woolly Mammoth with just Pinch and Volume controls. He wanted me to remove the Wool pot simulating it being set fully clockwise, and remove the the EQ pot and simulate it being set dead centre. The Wool pot was … Read more
A more compact layout for the Fuzz Factory using radial caps, so I thought I’d add a new post rather than add it to the old layout, to avoid confusion as this one obviously isn’t verified yet. Info about the original: This is a five-knob fuzz using two new old-stock sixties germanium transistors. The circuit … Read more
I’ve already posted the dirt side vero so I thought I’d redo it for the complete one with SHO. This ended up pretty compact so will easily fit in a 1590B. Updated 5th Jan 2014 – ground link added to avoid 2 ground connections to board. LED current limiting resistor also added to make use … Read more
