Here is a list of the schematics that are exclusive to this site. We created several and we have redrawn some schematics that were already available on the internet for readability or ease of use (these needed an easier-to-read format, corrections or part identifiers). Many of these schematics include “modernization” that are included and explained in the “Project” for the given schematic. You may freely post links to any of the pages or files on this site, but please do not put copies of these files on your site. We frequently update our files. If you want to see photos of the original units of any of these guitar effects see our “Originals” board on Pintrest Note: All Trademarks mentioned here belong to their owners and not to General Guitar Gadgets
