Detailed build document in English!

I think that the Big Muff is a very nice build for beginners. It is quite a simple circuit, and very easy to mod. It is a great way to learn which component does what, and to create your own circuit!

Here is an example of a pedal I assembled with this PCB. More pictures of pedals made by customers on the Coda Effects Facebook page!

It is a double sided PCB allowing you to make your own Big Muff. I also added an optional mid potentiometer. Thus, you can make any Big Muff version you like, including "boutique" variants with a mid potentiometer (Hoof, Iron Bell...etc)

High quality PCB :
  • Gold plated pads
  • Double sided board
  • Spaced pads for easier soldering

The parts names are the same as the ones used on the Big Muff page. This awesome website lists all the schematics of all the versions of the Big Muff! Thus, you can easily build any version of the Big Muff by looking at the Big Muff page. I also asked the owner of the website, who wished me luck!

A very good Big Muff pcb. The documentation is brilliant. It lists all the values for the parts of the most important Big Muff versions. What I like best about it is the mid pot. It really is an improvement. In addition to that you can find a description of how to build a black arts toneworks pharao with this pcb on the coda effects page.


How do I order one of these and the black hole..I can't figure out how to add stuff to shopping cart


I just purchased this board and I am confused about something. You have the R1 slot on your board above shown as R30 and there is no R31, or R1. the date on the board is 2020
