    Black Mirror VII: Obsidius on steroids!

    Finally finished this sucker today! Took a while with this one. Had a debacle over some REVV builds and ended up with some store credits on the PCB Guitar Mania site. I had already built an Obsidius Preamp but really wanted something closer to a Darkglass Microtubes B7K. Picked up a Black Mirror...

    Parentheses Fuzz: Popping when Distortion or Boost engaged

    Ok, folks...interesting little quirk with my Parentheses Fuzz builds. Basically, a pop is heard when the foot switch for either the Distortion or Boost is clicked. Distortion is much worse than the Boost. Usual fixes don't seem to work. Tried a 10k and 1M resistors on the input and output to...

    Pharmacist Overdrive: Red pill...or blue pill?

    Many of the Pharmacist Overdrive pedals I've seen seem to always be inspired by the original...which has an obvious Beatles motif. I wanted to go against the grain a bit. So, I figure why not make it more of a Matrix inspired thing, thus the whole "red pill / blue pill" thing. Turned out pretty...

    Closed Circuit Booster Limiter: Feel the power of Mjolnir!

    In a video on Angus Young's rig, they talked about a rather important piece of equipment that appeared to be pretty critical to his tone: the SoloDallas Schaffer Replica, which replicates the preamp section of a Schaffer Vega wireless system. I was quite intrigued by this and wondered why this...

    Hyped Fuzz (with fuzz mod)

    I built this one to replace an AionFX Hypercube Fuzz that wasn't working right. Seemed like one of the fuzz modes was missing a lot of treble and felt way too bass-y. I purchased a Behringer Super Fuzz SF300 to verify this. Figure that would be enough to test things...and it was. After learning...

    AionFX Solaris: Germanium Fuzz Face

    A month or so ago, I received a nice batch of Germanium transistors: some MP20A's and GT402B's to be exact. The MP20A's are generally low in hFE, around 50 to 80 on average. The GT402B is comparable to a AC132 with a bit higher hFE's that can get up to the 120 to 140 range. The idea was to have...

    SOLVED AionFX Solaris: Weird grounding issue

    Hey folks! Trying to finish up on a build of an AionFX Solaris pedal but ran into a weird issue. Basically, if nothing is plugged in except power, the pedal turns on and off, no problem. If I plug in the input and output the LED comes on, stays on, and nothing works. Bypass works....but...

    AionFX Binary Fuzz

    Finished putting this one together. Borked the hell out of one of the 8-pin sockets so I had to redo the PCB. Kinda, sort of Matrix inspired with the design. Pretty gnarly bass pedal for sure. Not at all what I expected. It definitely has that Darkglass thing going on though. Only thing I need...

    FV-1 Development ready to race

    Finally finished my FV-1 Development pedal. The name made me think about Formula 1 racing thus the inspiration for the design. Had some issues getting this thing to connect with my Mac. I have a new MacBook Pro with the new M1 chip so none of the usual drivers would work. Plus, with Parallels...

    Problem burning EEPROM with hex file from SpinIDE

    Ok, so I got my FV-1 Dev pedal all built and hooked up. Got the CH341A drivers on my Win10 laptop installed and the pedal is recognized properly. The AsProgrammer app recognizes the EEPROM and can read it. However, when I take a hex file produced with SpinIDE and try to burn it, it throws back...

    AionFX Argent and Halos: A Tale of Three Fuzzes

    So, as an experiment, I picked up a few PCB's from AionFX to play with. The first one is the Argent, which is based on the BOSS FZ-3 Fuzz. I recently picked up a FZ-1w to test out but ended up taking it back. Strangely enough, that one sounded super close to the AionFX Epsilon fuzz, which is...

    Muffin Factory: Sickly Sweet!

    I know, I know...three build reports in a row! Makes you wonder if this is all I do. :P This is probably one of my favorite builds I've done in a while. The build itself came together pretty quick. When I first saw the name "Muffin Factory" the only thing I could think of was cupcakes...

    Low Tide Modulator: Abstract for sure

    Another one I'm surprised I nailed on the first try. This is one of those pedals that I though for sure would have an issue after the initial build. While it didn't work initially after firing it up for the first time, I quickly realized that I needed to adjust the internal trimmers. Took a...

    Circulator: The mods made me go all vertigo

    I'm surprised I was able to nail this one on the first try, especially given that I used just about all of Chuck's mods. I initially designed it without the mod (thus the reason for the odd position of the rate LED) but after reading the thread about the mods I figured what the hell, let's build...

    Sunflower and Gnat Fuzzes: Experimenting with PNP Trannies

    Got a bundle of a few GE trannies and wanted to try them out. So, I got the Sunflower and Gnat boards to experiment with. I ordered a set of MP20A's and a set of GT402B's. I had used some MP20A's on a few previous projects and liked them. However, they tend to be on the lower HFe side so I got...

    SOLVED Muffin Factory: DIP switch board orientation

    Hey folks, So, I'm in the middle of finalizing a Muffin Factory build. However, while putting together the DIP switch board, I discovered what could potentially be a colossal f#$%-up. Seems the switch assignments don't line up with the labels on the faceplate. So...did I screw up and install...

    Russian Halo / Big Muff Civil War

    Finally got started on this set of builds for some stuff to put on Reverb. This one was stalled a few times. More on that in a sec. I started off wanting this thing to be as authentic as possible. So I procured a nice baggie of KT3102E transistors and built a test unit. So far, so good...but I...

    Fuzz Aldrin Deluxe Hybrid Fuzz

    Alright, so...like others have done with the Fuzz Aldrin, I decided to try out one of the mods for the Hybrid Fuzz Driver. However, instead of calling it the Hybrid Fuzz Driver, I kept the Fuzz Aldrin name (because I like it!) and just added Deluxe Hybrid Fuzz on the end. Updated the design...

    ThorpyFX Goodness: Shrapnel, Pyrocumulus, and Guardian

    Man...I've got a LOT of pedal builds to post but figure I'll pace myself. Quite a few built up over the past months so I'm just working through them. They're all part of a larger pedal study, looking at circuits, and seeing what does what. I've had my eye on some of the ThorpyFX stuff and was...

    Old World Paragon

    You know, for a larger pedal, this particular build went pretty quick. Really like how it turned out though. Built it using 1S1588 and BA282 diodes. Channel 1 is set with the low gain resistor and soft clipping with Channel 2 set with the high gain resistor and hard clipping. Had a problem with...
