  • Trem XVIII #2

    Trem XVIII #2

    A tremolo from the Stompboxoloy Newsletter. For more information and a schematic check out my previous post about the first build. I had some boards made at PCBWay.com. They prices are very reasonable. You get 10 boards for $5. That left me with a few spares. I gave a couple some friends to build. For […]

  • Scuzz Box

    Scuzz Box

    This is a a second build of Distort-O-Matic XI from Stompboxology. Read more about the first version of the project here and here, and a demo. The first version of the PCB had a couple mistakes which I fixed with this board. I designed the board to fit a 1590B enclosure. In the first build […]

  • Scuzz Box v1.1

    Scuzz Box v1.1

    This is a second version of the Distort-O-Matic XI from stompboxology. You can read about the first versions here, and here. Distort-o-matic XI is described as a distortion box with an aggressive tone control. In more concrete terms it’s a diode clipper and octave fuzz with with a two band active tone control 30db of […]

    Distort-o-Matic XI demo

    This is an audio demo of the Distort-o-matic XI from Stompboxology. Check out my build page for a schematic and images of the finished project.

  • Tremolo-Matic X build 3

    Tremolo-Matic X build 3

    This is a new revision of the Tremolo-Matic X from Stompboxology. You can read more about it here. In a nutshell, this tremolo splits the input signal into high pass and low pass filters and pans between the two. The sound is subtle and sweet. This type of tremolo was implemented with tubes in some Fender […]

  • Tremolo XXII v2.1

    Tremolo XXII v2.1

    I updated this design again. It’s almost ready for production. In this revision, I improved the PCB layout by moving the components that make up the LFO to the left side of the board and the audio path to the right side; this meant I had to move the shape switch to the other side […]

  • The Sultan

    The Sultan

    The Sultan is my first entry to the End of Days Fuzz Challenge. Based on the fuzz Face with a Bass and Treble tone control similar to tone controls used on Orange and Matamp amps. The Fuzz Face is a classic circuit. There are many Fuzz Face variants out there that sound great. The classic […]

    Distort-o-Matic XI Stompboxology

    Here’s another project from Nicholas Boscorelli’s Stomboxology newsletter: Going Discreet. Described by the author as: All-transistor distortion box with aggressive tone controls. Nicholas Boscorelli When I look at this I see a diode clipper similar to the Electra, DOD 250, MXR Distortion+, Proco Rat, and others, combined with a Super Fuzz octave Fuzz type octave […]

  • Tremolo-Matic XVIII Build

    Tremolo-Matic XVIII Build

    This is a tremolo built around a couple inductors, its from the Stompboxology newsletter: Going Discreet issue. If you’re not familiar, Stompboxology was a newsletter produced by Nicholas Boscorelli around 2002. It had many stompbox ideas, including circuits, layouts, and analysis. The Going Discreet issue is about building circuits with transistors. This issue has the best description […]

  • New PCB day!

    New PCB day!

    I have a few new PCB projects in the mail today. Flatline Compressor by John Hollis Titan Boost by John Hollis Tremolo-matic XXVIII from Stompboxology Distort-o-matic XI from Stompboxology Bobtavia by Bob Starr John Hollis John Hollis was one of the first people I ran into posting DIY designs on the internet. All of his […]

  • Tremolo-matic X by stompboxology

    Tremolo-matic X by stompboxology

    This circuit is based on a type of tremolo that some Fender amp models. Its operation is very interesting. It splits the signal path into a low pass and high pass routes and alternates crossfading between each. It has a sweet subtle flavor of tremolo. I had built this circuit years ago making a PCB […]

  • 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 […]
