  • Tremolo Matic XXII Stomboxology Update

    Tremolo Matic XXII Stomboxology Update

    I updated the Tremolo Matic XXII from the stompboxology newsletter by removing the single op-amp. It looked like this was used as an extra buffer for one of the reference voltages. Everything works without this extra op-amp but there is a distinct thump form the LFO. I made another run of boards via PCBWay.com. The…

    Tremolomatic-XXII

    This project came from the Stompoxology newsletter Volume 13 Number 2 published by Nicolas Boscorelli around 2000. I can’t find a copyright date on the issue. Stompboxology was very interesting and mysterious. The Stompboxology newsletters along with the Stompbox Cookbook would be hugely popular today. But they missed the timing for their prime audience. Nicolas…

  • Distort-o-Matic VI

    I’ve been fascinated by the Stompboxology and Stompbox Cookbook projects for a long time. I’ve only built a few and many of the ideas are hit and miss. The concepts presented are compelling none the less. The Distort-o-matic VI for example, uses a very off the wall concept. The input signal is imposed on a…

  • FM Modulator

    Here’s another interesting snippet from the Stompbox Cookbook. I was not able to get this to work. Who knows what went on in the mind of Mr. Boscorelli? Looks like the guitar signal is meant to modulate the frequency of the 7555 via pin 5. The 7555 then drives the 567, a phase lock loop,…

  • Ring Mod

    Here’s an idea for a ring modulator. I used a 3080 for the balanced modulator from the Ring-Modu-Matic. I used an envelope, from the Meatball,  to control the carrier frequency. This is untested. The controlling the FET to turn on the carrier is going to be a challenge.

  • Ring Modu-Matic take two

    There were a few mistakes in the last version of this. Here’s an updated schematic and PCB.

  • Ring Modu-Matic

    Here’s a PCB and Layout for the Ring Modu-Matic. I have yet to build this yet so use these files at your own risk! The dual gang pot in the lower corner I can’t get rid of, due to my lack of skills with Eagle. Notice the lines connecting the pot to pads on the…

  • Tremolo FX Loop

    This is a first draft of an idea that I have been thinking about for a few months. It’s a Tremolo that pans between the input signal and the signal coming through the FX Loop. If no signal is coming in to the FX Loop it would act as a normal Tremolo. Otherwise it would…

  • Distort-o-Matic XI

    This is an interesting distortion effect with an octave and wah like tone control. I redrew this schem from an issues of Stompboxology.
