AMZ is a resource with information about diy guitar effects pedals, stompboxes, audio circuits and tips on how to build them. There are fuzzbox schematics, signal booster projects, audio mixers and much more available free. Take some time to browse the site and discover information that can help you with your next DIY effects pedal project. You might decide to build your own clone of a classic!

Browse the free pedal building info in the Projects section, the Lab Notebook, the Guitar FX blog or many of the links in the left column. Enjoy!

PC Boards are available for purchase for many of my projects, including the AMZ Mosfet Booster, Mini-Booster, SOS overdrive, dpdt relay switch, power supply pcb and more!
