This is a project that I developed about 2 years ago for a rack amp system I was working on that has been put aside for now, so I decided to adapt the circuit for pedal use since the programming for the micro had already been done.
This is a 1″ x 1″ pc board which holds an AVR microprocessor that is controlling a latching DPDT relay. The LED indicator on the pedal is also driven by the micro. The soft-touch momentary switches that are shown several posts below were bought for this project.
You can use the pcb to build a new pedal, or retrofit it into a Boss or Ibanez box to give them true bypass.
More info is available here.
Back in 2002, I published an article about pickup simulators in the
Lab Notebook. The simple circuit can be built in a small metal box with in and out jacks and used as an “unbuffer”…

First pictures have been submitted of a completed power supply using the AMZ pcb. Thanks to Gordy for permission to post his pix. Nice job!

First look at the new AMZ Tweed Stack pcb. This project is an update of the classic Booster 2.5 combined with some of the features of the Mini-Tubes Preamp from the AMZ-CD. Several boutique builders offer commercial boxes that are based on this classic project, and this pcb will have plenty of mods to apply to the circuit.
Make a high gain stack-in-a-box or a smoother less distorted analog amp sim. Coming soon!
Here’s a sneak peak at the first project based on the Multi-Fuzz pcb. Some basic testing has been done and now it’s ready to mount in an enclosure.
