This is the classic foot switch found in wah pedals and older effects. In the old days this was the switch, 3PDT switches were not available or were very expensive and hard to get. These days these switches are about $10 each! And they don’t have the extra pole for an easy LED indicator and…

I got three boards from Pedal PCB. This is a pretty good project. It cost a bit more than the usual 1590B sized projects. It works well and sounds great. I’m keeping one and selling the other two on Reverb as a way to support my hobby. Check this out on my Reverb shop. Or…

Built and test this second version of the 22/7 by RunOffGroove.com. Sounds good. This is a great alternative for Big Muff fans. The OSHPark project is public and verified. 22/7 is a Big Muff built around CMOS inverters in place of the transistors used in the traditional BMP circuit. The CMOS inverters have a tube…

Here’s a purple sparkle op-amp Big Muff Clone. This fine specimen is for sale on my Reverb shop. If you’re in familiar, the Big Muff circuit is built around 4 transistors for all of the different versions except for one version made in 1978. This version has am similar but unique sound and was built…

This Haunting Mids clone is on sale on my Reverb shop. If you haven’t heard of Haunting Mids, this is not a clone of the JHS Pedal with the same name, it’s DIY community variant of the Big Muff. It has a great sound and stands on it’s own in the field of BMP clones.…
Found this blog post about a tour of the Electro Harmonix factory. It’s all in Japanese but the pictures are great. https://yhosokawa.myportfolio.com/dream-factory-by-electro-harmonix

Harvesting parts from these old PCBs. I had this need for a A100K pot and Christmas 🎄 has holding up the deliver from Tayda Electronics. So I started digging through my bin of old projects that never made it into a box 📦. I didn’t my ideal A100K pot, it would have been 16mm with…

I was trying to up the quality of my builds and thought about shielding and noise. Did a little research on the interwebs and came up with a few tips. First a little background. High gain circuits often run series of gain stages in series. If you have an input stage of x10 followed by…

This is the second version of the UBE Screamer board. This version fixes a mistake with the reverse polarity diode. I’m calling this ready for public consumption and will add it to the OSH Park projects pages soon. The enclosure is grounded through the jacks. The bottom cover though doesn’t make an electrical connection to…

The most fun DIY build you can make! This is my version of the Ugly Face Tim Escobedo. Great box with a unique sound . Not your typical fuzz or distortion box. Build your own from my OSH Park PCB project or buy one of my builds from Reverb.

This was an Algal Bloom clone by Fuzzhugger. I traded this on r/letstradepedals. This pedal hits a great heavy fuzz without the dissonant overtones.

this is one of my favorite overdrives. With a dark smooth tone, it’s really an overdrive, rather than a low gain distortion. It really never goes into hard clipping which gives it an expressive dynamic range. I built this from a Procyon PCB from AionFX. I used a desktop mill to engrave the labels and…
