  • What am I missing?

    Assume there’s your favorite booster at the input, what is D2 doing? This is the most common clipping arrangement that I have seen. It seems that D2 does nothing. If the boost at the input is running off 9V then the you should have a single that is centered on 4.5V going past the two…

  • MosFet Range Booster

    Here’s a quick idea for a MosFet Range Booster.

  • BB sized template

    Here’s an image of a BB sized template. I have made one of these to test it. Someone asked about it so I thought I’d post an image. This image was created at 200 PPI.

  • Fretboard Journal

    One of the Ugly Face’s that I built got a mention in the Fretboard Journal. No picture though. Which is too bad. They took a picture of a bunch of other more common name brand things. Really Tim Escobedo should have gotten a mention. The people writing these articles need to educate themselves on the…

  • 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…

  • Tremolo-Matic X

    This is Tremolo-Matic X from the Tremolo Issue of Stompboxology by Nicolas Boscorelli. I have redrawn the schematic to make it easier to read. Hopefully this will be helpful to anyone attempting this project. This is Tremolo that pans between a treble and bass signal. It inlcudes controls to set the level for both the…

  • Ring Modu-Matic

    This is the Ring Modu-Matic from Stompboxology. I redrew everything in Eagle PCB. This is an interesting design. It seems to use several different supply voltages. There is a +9v, +4.5v and +5v, +2.5v,

  • 5 Knobs

    Here’s an idea I have been wanting to try in a stompbox. Small Bear carries post with long leads that can be used to mount the pot to PCB. I thought these might be good for mounting a board inside an enclosure. This is a clone of everyone’s favorite 5 knob fuzz. This seemed to…
