    PS Terrier Review rev 2

    I have finished my build of a revised Terrier Review, ProCo Rat copy built on the PedalPCB Muroidea Distortion (2025 update). Mods I may have learned a few things since my first build, in which I strictly painted-by-numbers. I breadboarded the circuit before I built it to evaluate alternative...

    Adding Parallel Out to Empyrean Deluxe

    I am building the Empyrean Deluxe from AionFX for someone else, and they wanted to have the XLR and parallel output from the original. The parallel out isn't shown on the tracing journal for the Darkglass Alpha Omega (or I am getting lost in the spaghetti). Is it really as simple as just running...

    Ohl Junction #2

    I thought I was going to build up my next Fuzz Debate this weekend, with more tuning and different NPN, but nope, turns out I оrdered the wrong 4PDT switch, so I grabbed another project that has a case waiting for the pedal. Here's my second build of the Ohl Junction, a PedalPCB Guvernator. A...

    Audio Jack Breakout PCBs

    I have created a Github Repository to share the KiCad files for PCB breakout boards for the Neutrik M-Series style audio jacks. There are variants for Lug or PCB mounts, and for JST-XH and JST-PH headers. I have verified the versions with JST-PH headers. gtfields13/SharedPCB

    PS Boyle's ¬ Law

    I have finished the last new build from my first batch of printed cases. This is the Boyle's¬Law, based upon the Keeley Compressor Deluxe, using the AionFX Aurora Deluxe PCB. (¬ = "not" math symbol). This one took a trip to the Troubleshooting forum first, where @Nic was sharp-eyed enough to...

    Sheepy Love GS808 (Vintage Dual OpAmp TS808)

    Just about a month ago, @MichaelW was kind enough to send me one of his extra SheepyLove GS808, laid out by @szukalski. When I got back from vacation, I looked over the board and put it an order for the components that I didn't have on hand (a 51pF capacitor and W-taper potentiometer - never...

    PS Ohl Junction (Marshall Guv'nor)

    This week's Phido Sound new build is the Ohl Junction, based upon the Marshall Guv'nor, using the PedalPCB Guvernator PCB. I finished this a week ago, but was imagining that I might put together a demo for the sound. Given that my guitar playing is not that exciting, and this pedal isn't...

    SOLVED AionFX Aurora Deluxe - Basic Question

    I finished wiring up the aurora deluxe and I definitely have some troubleshooting to complete. I have sound and bypass, but only on one side of the blend. So my really basic starting question is - which direction (CCW or CW) is the clean vs the compressor for this circuit. In my case 10 (full...

    Substituting BC549C/BC559C for 2N5087/2N5088 pair

    I am building a second copy of the AionFX Sunstone (EHX Small Stone), and I wanted to know if I will see significant difference in replacing the 2N5087/2N5088s in this circuit with a BC549C/BC559Cs. I know the BC's have to be rotated 180 degrees, but will I notice any appreciable increase in...

    Fujitsu Mini Relays

    Pulling this over from: https://forum.pedalpcb.com/threads/what%E2%80%99s-on-your-workbench.13146/post-355537 What sources do you have for the Fujistu Relays used in the relay switch boards like in the link. I see these at Mouser at $4.43. As much as I like the idea, it seems like I'm cheaper...

    DEMO PS Argand Plane (EHX Small Stone)

    Rolling out the new builds, my next Phido Sound build is the Argand Plane, based on the EHX Small Stone, using the AionFX Sunstone PCB. This is my first build on an AionFX pcb. The PCB layout is nice and the build directions are easy to follow (I am sure I am not the first to say that). I...

    DEMO Fuzz Face (PS Fuzz Debate 01)

    With my other business (dead espresso machine) out of the way, I am finishing up the pedals that had been waiting for the box-o'-pink goodies that finally arrived from Tayda. First up, my 2nd Phido Sound pedal, a Fuzz Face built on the PedalPCB Twin Face PCB. I completely built out the...

    Rat Circuit Behavior - Output Stage Biasing

    I am setting up to build my next iteration of my Rat clone (Terrier Review) and decided to breadboard the basic Rat circuit from ElectroSmash, so I could evaluate alternatives to the LM308 OpAmp and the filter behavior. I was working from the ElectroSmash ProCo Rat analysis, but with my own...

    Fuzz Face - Does transistor selection really matter?

    I think the answer is, not much... I've been breadboarding the standard fuzz face circuit (see ElectroSmash Fuzz Face) with trim pots in place of R3 and R4, in advance of committing to solder on the PedalPCB Twin Face pcb. What I've been finding is that, when I iteratively adjust R3 and R4 to...

    Rat Terrier Build

    Occasionally my timing is perfect! My newly printed case and last parts arrived just in time for the Player Hater's Ball! This is my first complete build inside the Phido Sound brand with a printed case (and my 3rd DIY build on a PCB). It's a ProCo Rat using the Muroidea Distortion PPCB board...

    125B PedalPCB Muroidea Distortion

    Tayda Drill Template I have created a Tayda Drill Pattern for the PedalPCB Muroidea Distortion (ProCo Rat) fuzz pedal. There isn't a way to save notes to the pattern, so here are the deviations from the standard PedalPCB layouts The in/out jacks are set for the Neutrik NMJxHC enclosed, chrome...

    Update Muffin Fuzz + Kliche Overdrive

    I want to update my post on my first two builds (PPCB Muffin Fuzz in Stomp '75 build and Kliche Overdrive). After living with these for a week, I tried switching out the diodes on the Fuzz for germanium or LEDs in various combinations, but in the end I've decided I like the way the 1N4148...

    Centaur Clone (PPCB Kliche)

    I am back with my second build, the PPCB Kliche Overdrive that I bought at the same time as the Muffin Fuzz pcb. I setup the Big Muff Pi as the Violet Ram's Head with the idea that putting a Centaur in front of it would fill out the scooped mids, and so it was time to get this built. In between...

    REQUEST Anyone build a template for Muffinator Fuzz?

    I have the Muffinator Fuzz in my build stack, and wondering if someone had already made a Tayda drill template for this? It looks like it would be a modification to the Muffin Fuzz, with the diode switches located appropriately.

    First Build - Cherry Pi (Muffin Fuzz - Stomp '75)

    I finished my first DIY pedal from a PCB today, and am really excited about how it turned out. For small background, I messed around a little bit like 40 yrs ago, building a fairly primitive fuzz circuit from a 70's Popular Electronic article (Craig Anderton's Optimum Fuzz). I just have to say...
