    Dynamic Haircut v2.0 (Barber Gain Changer)

    Here's a complete do-over of my "Dynamic Haircut", which is a clone of the Barber Gain Changer. Here's the build report for v1.0, which I did almost four years ago. I sold that build a while ago. I had long since given away my last v1 PCB, and someone recently messaged me asking if I had any...

    Sliver Overdrive (Barber LTD SR)

    Here's my build of the PedalPCB Sliver Overdrive, based on the Barber LTD. I used the component value substitutions in @Route14's post, Sliver -> Barber LTD SR to build this to LTD SR ("Special Recipe") specs. It's a straightforward build, nothing unremarkable in that category. I built it in...

    Buffer + Bypass "Quasi-IC" Module

    I also posted this to DIYStompBoxes, but it's not getting much attention over there, so I thought I'd see if it piqued anyone's interest here. In my pedal builds, for bypass switching, I generally prefer a buffered electrical bypass scheme (similar to typical Boss pedals). I've been doing this...

    AionFX Procyon (BJFe Honey Bee)

    Here's my build of the Aion Procyon, based on the BJFe Honey Bee. Kevin has a great writeup on the Honey Bee circuit, based on his extensive research and tracing this circuit. The short version is, there are several variants of the circuit, loosely based on which brand was selling it (BJFe...

    Hybrid Fuzz Driver Deluxe

    Here's my take on @Chuck D. Bones's Hybrid Fuzz Driver Deluxe. A long time ago, I built the Skreddy "Holy Trinity" using PedalPCB's Aldrin Fuzz PCB: The Lunar Module (Aldrin Fuzz stock), Hybrid Fuzz Driver, and Screwdriver. I've done a lot of builds using this core topology. One of my...

    Debugging a short?

    I had an interesting experience this weekend. I went to add my CDB-mod Animals Diamond Peak to my board, and when I plugged in the power adapter, a digital pedal on my board (Boss GT-1000CORE) rebooted. I thought that was weird, and then I went on to notice that the Diamond Peak wouldn't turn...

    Aion Tachyon #2 (Boss SD-2 Lead Mode)

    This is my second build of the AionFX Tachyon Amp Overdrive, based on the lead mode of the Boss SD-2. My first build was about two years ago. In a decluttering frenzy, I foolishly sold the first build, and later wished I still had it. I recently built the Angry Charles hoping to scratch the...

    Old Fashioned (Skreddy/Animals Major Overdrive)

    Here's my take on the @HamishR & @Chuck D. Bones collaboration, the Old Fashioned, which is a tweaked Animals/Skreddy Major Overdrive. It's a YASF (Yet Another Skreddy Fuzz), based on the same topology as the Lunar Module (PPCB Aldrin Fuzz), Screwdriver, Hybrid Fuzz Driver, etc. My...

    Churl of Toan (custom BB/POT mod)

    Here's my Churl of Toan. I've been try to declutter most of my infrequently used pedals, but I've held on to my Pauper (Prince of Tone). I recently started using it, and remembered why I didn't sell it. I never use the OD/distortion switch (it stays parked on OD), nor do I use the internal...

    Ever had a JLCPCB manufacturing defect?

    So tonight I finished up a pedal based on a PCB of my own design. And when I powered it on... nothing! After some debugging, I found that one of the signal nets was shorted to ground. I narrowed it down to what I assumed were three possibly bad components. Fortunately, this part of the...

    Catalinbread Varioboost - Custom SMD PCB, 1590B Top Mount Jacks

    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...

    Scenario Preamp (Cornerstone Gladio SC)

    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...

    Angry Charles (JHS Angry Charlie v3)

    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...

    Gigantic Sauce Container (Way Huge Saucy Box) - Snakeskin SMD Edition

    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...

    Custom 3-in-1 (Naga Viper, Scarab Deluxe, Super Duper)

    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...

    Gigantic Sauce Container (Way Huge Saucy Box, custom PCB)

    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...

    Effects Layouts Spice Runner (Way Huge Saucy Box)

    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...

    Lamb Chop (Way Huge Pork Loin) Clean "Buffer"

    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...

    Trimpots: single-turn vs multi-turn, drift over time?

    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...

    Median Compressor (Wampler Ego 76)

    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...
