    Wah-like enclosure with extra space (like a whammy pedal)?

    Curious if anyone’s tried making a whammy-like enclosure, with a treadle and room on the side for foot switches and other controls. This is in pursuit of the coveted all DIY pedalboard, for better or worse. Now that I’ve picked the low hanging fruit, and some higher hanging fruit, I’m looking...

    LLMs and KiCad

    Looks like some pretty big leaps in automated PCB design. Makes me wonder if it will generate a whole new crop of YATS peddlers peddling their pedals, similar to the pandemic boom. https://eebench.org/blog/can-ai-design-circuit-boards-yet/

    PPCB Dog Byte Fuzz aka Mellowtone Wolf Computer

    I didn’t investigate this before I built it. I tossed it in the cart on a sale day because it had a cool name. I could not believe how this thing sounded with such a simple circuit. You can get normal tones, mis-biased gatey fuzz, self-oscillation, octave-down and descending arpeggio glitches…...

    12-band EQ?

    I’ve had this idea kicking around in my head about using two 6-band EQs (which I have) in series in a 1590XX. 36,63,110,190,330,580,1000,1700,3000,5200,9000,16000 Adjusting the filters of the gyrators seems straightforward using the AMZ calculator. But the 3.2k band is not a gyrator, it looks...

    DEMO Funbox DaisySeed - Eris: The DLU (Delay Line Utility)

    This is one that’s been kicking around in my head for a while. Delay is the foundation of time-based effects. But most guitar pedals are dialed in for a subset of these. The first notable thing about this delay is the TIME knob. The first half of the rotation is < 40ms, and then after that it...

    TerrariumSE - PolyOctave

    I haven’t seen a build report for this PCB yet. I dig it- a digital pedal platform with a standard 3-knob layout and true bypass. This is a fork of the terrarium-poly-octave by @Steve Schulteis , adapted to this layout. Mainly, removing the -2 octave voice and fiddling with the filters a bit...

    TerrariumSE - Question about pins being used

    On the TerrariumSE, the pots are labeled GPIO 16, GPIO 17, GPIO 18. When I followed the traces and looked at the Daisy Seed docs, I saw ADC0, ADC1, ADC2 Where do the ref labels on the pcb come from?

    PPCB Bad Mamma Jamma

    Rose gold enclosure, mocha aluminum knobs. Stomp Box Parts had W20K potentiometers with a center detent, so I utilized them for the EQ. I had two MC33178s pre-soldered to DIP8 breakout boards, purchased from the shop here. For the third one I ordered a stash of MC33178s and soldered it to a...

    Quicklime Girl

    Here’s chuck’s thread about this circuit: https://forum.pedalpcb.com/threads/this-week-on-the-breadboard-the-quicklime-girl.28098/post-364039 I like it- I can get that blown-out sound, and the gain stages provide a variety of tones. It was fun with a tele. Thanks @MichaelW for the board!

    PPCB Raincoat

    I have a cycle of expanding my pedalboard, adding more sophisticated programmability along the way, and then I hit a threshold where it’s too much and it distracts from just playing the instrument. I pared down over the weekend, and I found myself wanting to add a fuzz to the board. I have...

    Am I understanding RC filters correctly?

    I’m a hobbyist with almost no background in electronics, but I absorb some info from reading stuff on the forum. I wanted to see if I understood this capacitor change correctly. I have a raincoat. C6 is 10nf. I didn’t have one, but I did have a 12nf, so I used it. Does this create a high-pass...

    DEMO Ceres: Envelope Filter with 3 modes and full MIDI control

    This all started with a wishlist post about the “The Noise”. I felt like a copycat effect was doable using the daisy seed. But along the way, I built a workflow where I tell AI what I want to do, compile and flash, try it out with my guitar and amp, and repeat. I realized I could make any...

    C2CE Mirage Tremolo

    The c2ce projects are so nice to build. Well thought out design, great docs, provided tayda drill templates, graphic art for uv printing… I went with the true bypass option on this. The preamp side of this can get some very nice grit on it. The tremolo has a very satisfying LFO wave shape. I...

    Squidward 1590LB top jacks

    Here is my 3rd ringer. This time it’s stock except I used matched 1N60s. No bypass- I don’t need it. It’s going to be plugged into a loop switcher. It will save precious real estate by being tucked into a small gap of unused space. Does not work with all jack sizes 😆

    Aion Comet / DS-1, modded vintage version

    Appreciation of the DS-1 is relatively new to me. By the time I picked up an axe in the late 90s, I equated that $40 orange pedal to awful tone. I’ve learned a lot about pedals since then. I knew there had to be something special about it since I like recordings featuring the DS-1. This is my...

    Ring Leader (modded PPCB Squidward)

    The green ringer is one of my favorite pedals of all time. For years I played in a band where it was the only device between my guitar and my amp. This variation is the @DGWVI special (build report for that one here). 5817s for the diodes, 5087 for Q2, 10K pot for R4. One may call these knobs...

    Bass Klon (1590B content)

    This was built on Aion’s “legacy” Refractor PCB. It’s the first completed build for the Bass pedal board I have planned out. It took a bit of digging to find the actual mods. I went off a photograph of the list of mods from this build report. I then compared the PPCB schematic to the Aion...

    Scarab Redux

    I love the Scarab Deluxe. It sounds great at all settings, it can go from OD to Distortion to Fuzz. It’s low parts count with no rare parts. So I did my typical 2nd build- remove controls I don’t need/change, fit it into a 1590B. As usual when I do stripboard, I go in with a vague wiring plan...

    PPCB Phase II [1590B]

    I’m excited about wrapping this one up. I love the Duo-Phase, but it’s large. While I really like two phasers, I can do my thang with one phaser. This board has a compact layout. Which is cool, because I was able to fit it in a 1590B, my preferred enclosure size. I used the 2.5mm wide 470nf...
