Here's my latest spin of the Catalinbread Varioboost circuit. My gateway to this circuit was the PedalPCB Mercurial Boost. I then made my own custom PCB of the circuit, with integrated relay bypass, and all three knobs on the same horizontal line. Now I took it a step further and shrunk it...

Here is my build of the Scenario Preamp, based on the Cornerstone Gladio SC. This was a client build. This is my first build for a new client, with whom I have now officially doubled my client base! (*) This was a very straightforward build, both because it uses common parts, and also because...

Here's my recent build of the Angry Charles, based on the JHS Angry Charlie v3. I wanted a higher-gain MIAB-type sound, as I've been working on learning some Iron Maiden tunes. I'm not looking to duplicate that tone exactly, but just do a reasonable approximation. I don't really have any...

My latest overdrive obsession is the Way Huge Saucy Box. The Effects Layouts Spice Runner was my gateway drug. I liked it so much, I quickly whipped up a custom PCB for the circuit, calling it the "Gigantic Sauce Container". That design was notable in that it was my first time using a...

This is a prototype 3-in-1 build for a client (my one and only client). When he engaged me for the phaser build, he was also asking about fitting three circuits into a single enclosure. Ideally he wanted all three in a 125B enclosure, but we settled on a 1590BBS. He's a fan of my soft-touch...

I've really been loving this Effects Layouts Spice Runner (based on the Way Huge Saucy Box) that I built recently. Enough that I felt the circuit deserved my custom PCB treatment. Here I present my "Gigantic Sauce Container". The circuit is interesting in that the drive knob is a dual-gang...

Here is my build of the Effects Layouts Spice Runner, based on the Way Huge Saucy Box. From what I've gathered, based on Internet hearsay, this is a simplified version of the Way Huge Pork Loin (for which PedalPCB offers a board, the Lamb Chop). Just by looking at the schematics of the two...

I was looking at the schematic for the PedalPCB Lamb Chop, which is based on the Way Huge Pork Loin. See also the Effects Layouts Spice Runner, which is based on the Way Huge Saucy Box. Internet hearsay suggests the Saucy Box is a simplified version of the Pork Loin, and a quick glance at the...

I'm sure most of us have encountered a build that required a trim pot: a small potentiometer that is soldered directly to the PCB, often intended to make some one-time adjustment that accounts for variability in another part of the circuit (e.g. bias), or maybe some kind of tuning that is...

Here is my build of the Median Compressor (based on the Wampler Ego 76). This is actually my second build, as I mentioned in this thread, the first build wouldn't bias correctly with the through-hole 2n5457 JFETs I used, and when I replaced them with SMD parts, I lifted a trace. Though I think...

Here's my build of the Stagecoach Overdrive, based on the Barber BUSS fww Edition. I'm not even sure what prompted me to buy this. And I probably would have sat on it, except that, several weeks ago, I drilled the enclosure for it. I drilled the enclosure thinking I had already populated the...

This is a clone of the Skreddy Lunar Module based on a custom PCB of my own design. A few years ago, I built this circuit using the PedalPCB Aldrin Fuzz board. I also used the Aldrin Fuzz board to additionally build the two variants, the Screwdriver and Hybrid Fuzz Driver (thanks to the great...

One of the main reasons I build my own pedals is that I mostly enjoy the process. And I definitely find it satisfying to play through something I built myself. As such, the "more DIY" something is, the greater the satisfaction. And with pedals, that has been a progression of: kits, to...

Says the rest of the forum, "Sheesh Matt, haven't we seen this a few times already?" Yes, but I finally got it right! I started with the Aion Cepheus. Then I made a custom PCB version of the circuit that had all kinds of problems, and though I got it working, it was too nasty to post a build...

I recently posted a build report for my AionFX Cepheus. I kind of rambled on in that build report, but it turns out I really like it. The only thing I don't like is the mechanical 3PDT switching, as I've become a soft-touch snob. I have various bypass modules, but I'd need to do a custom...

This is in regards to the Median Compressor. I initially had a similar problem as @ninjagrips as described in this thread. I initially built my Median with some TO-92 2n5457s I had in my stash. But like ninjagrips, I could not get the S-G voltage anywhere near 1.875V. However, in this state...

Referring to the schematic for the Chauffeur Overdrive (Shnobel Tone Daily Driver). If I'm reading the schematic correctly, this circuit uses a 7660SCPAZ charge pump to generate a negative power rail. And then all the RC4558 opamps are powered with a bipolar supply. So far so good. Assuming...

My client (my one and only client!) requested a phaser. He wasn't sure between a Boss PH-1R or EHX Small Stone. But, as always, the community here was extremely helpful. We ended up going with the Boss PH-1R clone via the AionFX Emerald Resonant Phaser project. It's a fairly densely-packed...

Edit: see the great, more comprehensive tutorial on these waterslide decals by @Guardians of the analog (GOTA): The 2026 revised film free decal tutorial. What follows isn't intended to be a tutorial, but more of a living notes document, particularly with regards to using Sunnyscopa's new...

This is my build of the Aion Cepheus Amp Overdrive based on the Cornish CC-1. Aion's description of this pedal and Cornish pedals in general is good; he goes into even more detail in the tracing journal. The same board can be used to build the higher-gain GC-1; Aion's build docs have the BOMs...
