SRV Special… The SRV Special is a modified Tube Screamer Circuit. Some capacitors and resistors are left, to make the sound more pure. Furthermore 1M or higher is used for the GAIN pot to increase the GAIN range of the pedal. The pedal is an approach to get closer to Stevie Rays Sound… The Mods … Read more
FSB member Mictester came up with this design a couple years ago. Utilizes 4 transistors, 1 PNP and 3 NPN, though you could probably use an NPN in place of the PNP. Best to socket and try a few different transistors. The schematic says BC213L for Q1 and BC183L for Q2-4, but any medium gain … Read more
7 weeks I’ve had a bloody trapped nerve in my back now, but I thought I’d better at least attempt to concentrate enough to do a layout every so often so you don’t get bored. The B%st pot is just a second volume control with the B%st stomp selecting between the two. I have shown … Read more
Mmolteratx traced this one over on FSB. Figured I’d put it up. Seems to be a BossTone derivative with some tweaks. Here’s the original: And since all the offboard wiring is making a few people say, “WTF,” here’s the rat’s nest that is the offboard wiring for this effect. The “In” and “Out” wires go … Read more
General The Axis Face Silicon is a Silicon Fuzz Face Circuit with some mods. The schematic and description of the pedal can be found at Fuzz Central: http://fuzzcentral.ssguitar.com/axisface.php Basically there is a additional pot called “Smooth”. The more the control gets dialed clockwise, the smoother and overdrive like the fuzz gets. With this control its … Read more
There are a lot of versions and subversions of the Big Muff. Many consider the Violet Ram’s Head to be the best, though many consider the Triangle, or IC, or Green Russian, etc. the best. YMMV This one has the pots hard mounted to the board, though depending on the enclosure you use, it may … Read more
First The Clark Gainster is a rare and not too hyped drive pedal. Its one of the sweetest sounding drive pedals ive ever heard so far though. The clark gainster has a very simple circuit, but sometimes less is more. The gainster can be built with Mojo parts or not. This article is more about … Read more
General The Iron Bell is a big muff variant based on the P19 version of the muff Here is a interesting link with a lot of schematics: http://www.bigmuffpage.com/Big_Muff_Pi_versions_schematics_part4.html In addition to the Big Muff there is a fourth pot for the mid range, called colour 😉 Schematic and BOM This schematic ive found in the … 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
Since I did the Blower Box yesterday, and it’s essentially a RAT, I figured it wouldn’t take too much effort to convert that layout to the original. So here’s the original ’86 RAT.
