    The Tremolo Matic XXII (Tremolo 22) is a great sounding tremolo. This is origianlly from Stompboxology. I’ve written more about it here. I made a few changes to the original design. This latest version adds a few improvements to the first couple revisions. I have been manufacturing these boards with They have a great […]

  • Small Time Build

    Small Time Build

    Small Time is a PT2399 delay designed by the Valve Wizard. This delay has tails. This allows the delay sound to continue after the pedal is bypassed. My first built worked well and wounded good. The tails was not as exciting as I thought it would but it is interesting and a small bonus. The […]

  • Prototyping Guitar Pedals

    Prototyping Guitar Pedals

    This is post for anyone interested in getting started making your own guitar pedals and prototyping your own PCBs. I like making guitar pedals and synth modules. I’ve built more than a few of each. When I started, some of the first modules I built were done on perf-board and strip-board, then I moved to […]

    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 is a great way to make high quality PCBs at a very reasonable price. The key is to order several […]

  • Stone Bender #3

    Stone Bender #3

    This sounds really good. I figured I’d build another and give to a friend, trade it, or try and sell it on Reverb. I made one of these on strip board and sold it at a swap meet. Here’s a post about the original circuit and schematic. I made an updated PCB check out the […]

    I found this PT2399 based delay design called Small Time on the Valve Wizard web site. These PT2399 delays can sound really good, and the Small Time has tails, which is a very interesting option. I had to give this a try. Delay Tails Tails, if you’re not familiar, is the effect where the echoes […]

  • Befaco A*B+C

    Befaco A*B+C

    Befaco A*B+C is a voltage multiplier and offset, every system should have one of these! This is a great little utility. I put it up there with Maths. It’s a strong recommendation I know. I really feel this module deserves a place in any rack because it could find a place in any patch! What […]
