    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

    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 probably […]

  • Boss Tonebender how about a Buzzbender?

    We’ll call this the BZ-1. What got me started on these Boss rehousings was seeing the Boss Tone Bender TB-2w going for 3k on Reverb.com. These were super cool pedals but not worth more than than the list price of $350. I understand the idea of scarcity and knew there were only 3000 made, but […]

  • 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. The “Boss” DRV-1981 Why? Good question! I suppose I saw the ridiculous prices people were paying for the Boss Tone Benders that had come out recently and […]

  • 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 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.
