  • Pedal workshop Noisebridge #3

    Pedal workshop Noisebridge #3

    Thanks to everyone who came to the last pedal building workshop at Noisebridge. I was impressed with the enthusiasm! We demoed some pedals talked about populating the PCB and identifying the correct parts and placing them in the correct locations on the PCB and soldering. The next workshop is scheduled for Saturday, March 4th, 1…

  • Bobtavia analysis

    Bobtavia analysis

    This is a quick look at how the Bobtavia works. The Bobtavia is uses the LM386 to amplify the input signal. In the default setup the LM386 has a gain of 20. The output of the LM386 runs through a 220µ C4 cap into a small audio transformer. The input appears at one output of…

    22/7 4069

    Here is a version of RunOffGrooves 22/7 using the 4069. The original circuit uses the 4049 Hex inverter. The 4049 is a 16 pin dip with 6 inverters. Here is the 4049UBE data sheet. You can see it has 16 pins with 6 inverters. There is a power Vdd pin 1 and ground Vss pin…

  • Big Muff clone

    This is another Big Muff clone. It’s a green Russian built with a Madbean PCB. I milled the enclosure. Big Muff clone was originally published on Super-Freq

  • Stompbox Studies – Class 1

    Stompbox Studies – Class 1

    Want to build your own effects pedals? A good place to start is understanding how transistors work. Transistors are those three-legged devices seen populating many stompbox circuits. Transistors are a core building block in electronics. Integrated circuits, like op-amps, are made up of many transistors! Transistors are used in all of the circuits you’ve heard…

  • Parentheses Fuzz #5

    I think this is #5 I’m losing count. These are so much fun to play the world needs a couple more! I used matte black sand textured enclosure. Which give this a good industrial vibe. This is a pretty easy build for what you get. The board is a good size and parts are comfortably…

  • Boss DRV-1981

    Boss DRV-1981

    This is a clone of the 1981 Inventions DRV rehoused in a Boss DS-1 enclosure. I used the PedalPCB Informant PCB and the MadBean Softie for this project. Why? Good question! I suppose I saw the ridiculous prices people were paying for the Boss Tone Benders that had come out recently and thought I could…

  • Stomp box enclosures and shielding

    Stomp box enclosures and shielding

    I was trying to up the quality of my builds and thought about shielding and noise. Did a little research on the interwebs and came up with a few tips. First a little background. High gain circuits often run series of gain stages in series. If you have an input stage of x10 followed by…

  • Vulcan v1.1

    Vulcan pcb built up. This is version 2.

  • Pile of PCBs

    Building some ugly faces

  • Vulcan by Joe Davisson

    This is Joe Davisson’s Vulcan overdrive. Starting with a prototype board made at home with the Othermill, then turned this into a board from OSHPARK. Boxed up and is working well. This is an interesting overdrive with a couple unique circuit features.

  • Box of Rock clone

    Box of Rock bootleg in process. Milling the box on the Bantamtools Othermill.
