  • Zap Frequency #3

    Zap Frequency #3

    I’m experimenting with the Harmonic Energizer. Read more about it in my previous post. I updated the PCB with room for two pairs of clipping diodes. With this update. Using the prototyping service at PCBWay.com is a great way to make high quality PCBs at a very reasonable price. The key is to order several […]

  • The Sultan v1.1

    The Sultan v1.1

    Heres an update to the Sultan. Read about my error in the first version of the pcb here. I made a mistake and the jacks grounds were not grounded on the first version. I ordered an updated board from PCBWay.com to move this project out of the prototype phase. This was my entry in the […]

  • Mother Fuzz

    Mother Fuzz

    This is Mic Testers Big Muff Plus. It’s a Big Muff with a JFET input and output stage, and a James control in place of the BMP tone control. The JFET input creates a higher input impedance the on the original Big Muff which prevents treble loss. Schematic Q1 is a high impedance input before […]

    Made a few enclosure for some new projects today.

  • Harmonic Energizer

    Harmonic Energizer

    Here is a clone of the Systech Harmonic Energizer. This is a parametric EQ. It’s like a single-band equalizer with a control to set the width of the frequency band that it affects. It also has a control to sweep the frequency similar to a wah pedal. The Harmonic Energizer has been described as the […]

  • 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 […]

  • Flatline v1.1

    Flatline v1.1

    The first version of my Flatline PCB worked well but had a couple of small problems. Check out my original post for more information about the Flatline Compressor.  I fixed the issues with the original PCB, and had some boards made through PCBWay.com. The cost is only $5 for 10 boards, so it’s perfect for prototyping. The first […]

  • The Sultan Fuzz

    The Sultan Fuzz

    This is my entry in the End of Days Fuzz Challenge 2022. Based on the Fuzz Face with an added two band tone control similar to the tone controls on Orange and Ampeg amplifiers. I wrote about this circuit in this post: The Sultan. I was pretty happy with the sounds on the breadboard so […]

  • Stone Bender #2

    Stone Bender #2

    This pedal sounds so good I had to make another! Check out my first build and the build page. I manufactured these boards at PCBWay.com. This board is posted at the PCBWay Shared service. You can order and build it for  I milled a gray powder-coated enclosure. It looked better than I was expecting. It’s got a […]

  • Milling some new enclosures

    Milling some new enclosures

    I have a few new projects in the works. I’m doing this batch sort of assembly line style. I soldered all of the boards, now I’m milling and drilling all of the enclosures.

  • Rock Box

    Rock Box

    The Box of Rock is a great Marshall sound in a pedal. It includes a boost section also. Box of Rock is pretty amazing and sounds great. J. Mascis likes it so much that he had Zvex put two in one enclosure. But what if you wanted something more like an Orange amp? Here’s an […]

  • Flat Line by John Hollis

    Flat Line by John Hollis

    The Flatline is a compressor with a simple effective design. It works surprisingly well for its simplicity. I’ve built a few of these over the years on strip board. This time I decided to make my own printed circuit boards. Who is John Hollis? John Hollis was an early contributor to the DIY Pedal scene. […]
