    DEMO Kewpie Fuzz

    this build is dedicated to my late bun son Alvin 🖤 some may have seen his appearance earlier this year on a superfuzz build. after some months of ongoing chronic issues and deterioration, my partner and i had to let go our loyal companion of 8 years (euthanized). it’s been a rough few weeks...

    DEMO AionFx Ember Distortion (Amptweaker Tight Metal)

    ordered this for myself, but ended up building it for a friend’s birthday gift. i had high hopes for this circuit, it’s definitely gotten a lot of praise around many parts of the internet. it’s really hard to make fair assessments of pedals like this when i’m a lot more used to better tools...

    DEMO Byzantium Flanger (Boss BF-2 Flanger)

    this is my first flanger 🤟🥳 huge anticipation for this build. couldn’t wait to do this one. this is actually a really easy build for a double/stacked pcb. there’s lots of space, there’s really not that many components. and when it comes to wiring, having top and bottom boards covering...

    DEMO Face Melter (Steel Panther P Melter)

    this was a commission build for a friend. i nicked the uv print .pdf from a thread here somewhere (i would upload it here to share but i can’t find it right now) using the print as a guide, i marked out where i wanted the drill points to be, and sorta just winged it. the print doesn’t fit...

    Deflector Reverb - noise

    first dabble at FV-1. first time using the 'basic relay bypass' board. finished this a few weeks ago (pcb came with FV-1 presoldered) was super excited. sounds really cool. just wish i could get rid of this noise in this demo everything is at noon, except mix, which i turn up to noon to bring...

    DEMO Magnetron Delay (Keeley Magnetic Echo)

    Always liked the mad prof deep blue delay (seabed delay), it’s been on my board since i built it. until today. hot damn, the added modulation controls just makes this a clear step above a three-knobber. yeah its still got the lofi qualities of the PT2399, but tbh i love how this sounds for...

    DEMO Lead Solder Overdrive

    ever since this appeared in the project wishlist (same day it was released i guess), i’ve been bugging to try this circuit. boy howdy, we got there. and i guess it’s pretty good 🤷🏻‍♂️ its kinda hard to benchmark fairly cos i haven’t tried many circuits like this yet (still gotta do a brown...

    Blue Shoe Gai Pan (JHS PG-14)

    the next stop on my JFET distortion journey was this thing. when first looking at demos for it, i think it was probably paul gilbert’s enthusiasm and good nature that sold me on the trying this circuit more than the sound of the circuit itself. so it’s a maleficent mids (hauntings mids) into a...

    DEMO Figment Preamp (Acorn MIGFET 50P)

    despite my doubts that this would sound any good, i was still keen to build one and see how it goes. haven’t seen/heard many demos of the migfet on youtube, not sure what to expect. the board calls for a 125B, but i really wanted to have all the knobs inline, so i made it happen in a 1590BB2...

    DEMO [Vero] Univox Superfuzz - altoids

    whilst in the middle of building x3 ppcb boards, i was watching/listening to a demo, and became fully compelled to build a superfuzz. that was it, i dropped everything, pulled up a univox superfuzz layout and started chopping up a vero board. i never intended to build this in an altoids tin. i...

    SOT-23 test sockets and measuring JFETs

    so after all the lurking I've done here - it has been thoroughly burned into my brain that JFETs are not simply plug and play and shouldn't be considered as such. my first attempt to measure JFETs for a phase 90 build went well. simply built the RG Keen 'greatly improved JFET matcher' on vero...

    DEMO [Vero] DEFX Hooke / Spaceman Orion (analog spring reverb)

    not sure why i hadn’t seen this circuit/build earlier. i guess not that many have built this one. but then one day i came across a vero build i saw on kaisertronics’ ig post. did a search and looked like a handful of folks here have built it and done so very very well. i was super keen on...

    DEMO rosamp SLO-100

    Around Jun/Jul Rosamp sold out of these - and then reopened with revised kits in September, and I reckon I probably got one of the first 100W kits off that batch, because when i opened the box, the transformers were off-gassing like a mofo 😷 Honestly the vapours were that strong I didn't wanna...

    DEMO ‘Deacy’ Brian May Ge PNP transistor amp [tagboard]

    originally built this back in jan2022. i decided to do a lil demo for it last night - but this time with an SM57/focusrite (instead of built-in iphone mic). the inspiration behind the build comes from the amp known as Brian May’s ‘Deacy’ amp - a germanium transistor amp that Queen bass player...

    DEMO Tagboard CE-2 chorus

    most sensible builders out there are putting time into designing takes/original circuits and PCB layouts on diptrace or similar, for efficient and reliable PCB/pedal production, and meanwhile here’s me regressing into veroboard and tagboard builds like a silly goose. after doing a few tagboard...

    [Vero] ProCo RAT

    i had this one on my list for so long, but it just kept getting bumped for other things i wanted to do more.. but a few weeks ago the other guitarist of a band im in asked about me building a rat for him. so i finally got it done. here it is i want to like it. but it’s not for me. tried...

    DEMO [Vero] Ibanez STL Super Tube

    this is almost exactly the same as the ibanez ST-9 / maxon ST-01 only difference is that the mid-boost freq control stage is moved to after the clipping stage, instead of before, as with the ST-9. ‘STL’ was apparently made for about a year before it was discontinued. so i built one to see if...

    LM317 power supply design (~33V DC) from 50V AC tap (tube preamp content)

    i am trying to design a power supply. but i am not very smart. i have a few limits with the design (and there’s a few reasons why..) 1) i’d like to use a LM317 voltage regulator since it’s available everywhere and low cost. 2) i have to use a 50V AC tap (reasons below) - unless i try to use a...

    DEMO Redshift (whetstone phaser)

    firstly, big thanks to @szukalski for sharing the UV print pdf design. it's so cool. so i heard people talking about the blueshift being a difficult/daunting build.. the blueshift was honestly fine, it's just a lot of components. but golly gosh this redshift was a real fiddly tedious bastard...

    DEMO Blueshift (Boss Dimension C)

    for the longest time i had no idea the boss dimension C is a chorus pedal. i always assumed it was just some obscure boss pedal thing. who doesn’t love a chorus? after building the CE-2, i was all about ‘em. then i found out what the dimension C actually is (+ roland dimension d) and it’s fancy...
