I think my build is working the way it is supposed to, so I didn't post in troubleshooting. I'm building a 2-channel loop switcher that is intended to be controlled by 2 switches connected via a TRS cable. I think I made several assumptions that were incorrect. My real question is: What would...

This one was mostly finished for a while. All the recent Phase 90/45 build reports inspired me to wrap this one up. I’m not normally a black & gold person, but every once in a while it just feels right for a build. I picked up a matched set of transistors from AionFX long before I had a board...

I wasn’t planning to write a report for this, but I didn’t find another report for this circuit. I’ll quote the product page for an overview: I appreciate designs the use common, inexpensive parts as an alternative to the “mojo”. I think this is a good beginner circuit, even with the three...

This is my third build of the circuit. My first was built to n00b construction specs, the 2nd as exercise in point-to-point, and this one is customized to fit into the design language I’m developing on my pedalboard. The TONE knob felt useless to be, so I ditched it. I felt sure that I didn’t...

The dirt expedition continues… I didn’t dive into tweaks and mods. The only difference from the BOM is a C500 for gain. I’m trying to make the insides cleaner on my builds. Getting the wires close to the board went ok. When I get low on my current supply of solder, I’m planning on getting some...

Let me preface with I don’t really know what I’m doing. I put 3 little circuit blocks together. The preamp from the Chelsea Muff, the HPF from the Karma Suture, and the Harmonic Jerkulator. When I probe from the jack in to the preamp out, it’s fine. When I probe from the Jerkulator in to the...

This is my 2nd Ugly Face- the first time I built a Nutty Fuzz. I don’t need to ever set the threshold, so I omitted it. First time putting an expression jack in a 1590B. It only worked well because of how small the pcb is. It behaves a little different compared to my Nutty Fuzz. A bit wilder...

This is for a friend- they wanted a reverb with a lot of controls on it. My experience with ℵ₀’s PCBs so far has been positive. Well thought-out takes of a circuit topology, clean layouts and a great fit inside the enclosure. I’m glad I grabbed two of these boards- this thing is flat-out fun...

Christmas Day build. As I continue exploring guitar pedal circuits, I finally made a stop at the Harmonic Percolator recently. A sound that is grimy and grating, yet has an interesting clarity to it. Last month I made my first percolator. I ordered the Antithesis PCB soon after. Nine times out...

This was a pain in the ass. I stuffed and unstuffed this 3 times. I have business cards wedged between both sides of the board. It’s not behaving normally either. The gain turns into velcro and then cuts out completely at 2 o’clock. Only the last 1/4 of the tone does anything. Besides that, it...

Right now I’m tapping wires to ground for switch presses. That’s fine, but I was wondering if anyone knew of some momentary SPSTs that I could stick in my breadboard.

This is a weird one. And I don’t mean cool weird. But it’s not bad weird either. Just weird weird. From Moonn’s product page: At first I really disliked it. I almost recycled it for parts right then. But I slept on it, just like any other pedal I don’t like the first time. Basically what...

I had this 99% done for months. I noticed there was room for these giant electros, which were the only ones I had at 220uf. I always love when a pedal has a faceplate. My art skills are limited. I’ve only tried this direct in. It sounds… fine? 🤷‍♂️ I wasn’t overly impressed by it. But I...

I bought this enclosure from Missouri Electrical Box Company a while back, and wasn’t sure what to put in it. I have an old Dano with lipstick pickups, and in my mind a Harmonic Percolator seemed like the right type of grit for it. Nevermind the fact that I’ve never built or even played one...

Hello. I have my first Harmonic Percolator that I whipped up last night. It sort of works. When it’s cranked, it’s about halfway below unity. When I switch to my hottest pickup and really dig in, it almost wants to get loud. It kind of makes me wonder if it’s misbiased or something. That, or...

I tried to encapsulate it all in the title. All the 220uf caps I have on hand are either 10v, or these clown shoe 50v ones that I’m not sure I can fit. Or, alternatively- does it need to be 220?

I like compressors on guitar. The pump, the thump. The squish. It’s been a sort-of side quest while exploring the wide world of gain devices. So far, I’ve built the Thumb Sucker, Closed Circuit Booster Limiter, Byrdhouse, and the Median. This build became practical after the THAT2159 became...

This came together quick. Sometimes it’s nice to have something simple to build with readily available parts. I used my budget materials on this. Raw enclosure, and pulled parts out of the scrap box. I really like this fuzz. It can get really saturated, and it can also behave kind of like a...

I liked that this pcb is small enough to fit into a 1590A. I assumed I would just build it in a 1590B so I could fit top jacks. Then I came across the Gorva M45. Just a bit bigger. I would have preferred to save my pcb-mount stereo jacks, but that’s ok because it helped me finish the build...

First off, shout out to @keyth72 for all the awesome Funbox / GuitarML contributions to the DIY and open source communities. https://github.com/GuitarML/FunBox This is my first Funbox Planet series build. This is using a build I compiled, so I can make some tweaks before I hand it over to the...
