    It’s Bandcamp friday!

    I’m a big fan of Bandcamp, it has everything I want in a music service, it supports consuming music by the album, and has great support for music creators. The first Friday of every month they give 100% of proceeds to the band! So today is a great day to buy some music! Here are…

  • Terrarium Rhythm Delay

    Terrarium Rhythm Delay

    I built the PedalPCB terrarium a few months ago. I Finally got around to installing some software and testing it out. I found this post on the PedalPCB forum. Sonic_explorer includes a link to a bin file for a multi-tap delay. I decided this might be a good place to start. I tried a few…

  • Frobnicator


    This is my second try to get this right. I designed a PCB for this earlier but the errors were too great to get around. Quick overview, Frobnicator is a tremolo by John Hollis, one of the original DIY crew. He designed a few very original effects that still exist on his site. Frobinactor is…

    This is a redesign of the Tremshifter by Dead Astronaut FX. It’s a tremolo and filter in one. There are two LFOs, one driving each the tremolo and the filter, with a rate and depth control for each. I built a couple of the Dead Astronaut boards and they worked well. I didn’t like the…

  • Super Frequency

    Super Frequency

    This is my spin on Tim Escobedo’s Ugly Face. The original is a great DIY project anyone that hasn’t built it should give it a try. Super fun, unique sound, parts are easy to get, and it’s not a difficult built. This version makes a few changes to the original. The original uses an LM386…

  • Bigger Muff part 2

    Bigger Muff part 2

    Looking at the Bigger Muff. Still not happy with this, it doesn’t sound bad it’s just that the range of the controls is unsatisfying. There are plenty of usable sounds some but some of the settings are not useful. Here is the schematic: Here is a BOM: Partlist: BASS A1M 16MM GAIN A100k 16MM_DUALSUSTAIN A100k…

  • Peach Fuzz Clone

    Peach Fuzz Clone

    I have wanted to try the Frantone Peach Fuzz for a long time. The circuit uses one of my favorite chips the LM386. Not only does it use the 386 it uses two in series. Frantone is one of the original boutique companies, starting in 1994! They went dormant for a some years but have…
