Muff'n Pedal Kit (Compare to Big Muff Pi™)

Pedal Parts and Kits/GuitarPCB

1 review Write a Review


This kit includes all of the parts needed to build the GuitarPCB Muff’n project. This circuit is based on the commercial Big Muff Pi™ pedal. As the commercial pedal was offered in many different versions/variants over the years, we are pleased to offer 4 different popular variants of this circuit as listed in the Muff'n Build Document: Triangle, Violet Ram, Civil War and Green Russian. Choose your desired variant from the options on this page and we will customize your order according to the values of that variant.

While there are a lot of modifications which can be made to this circuit, this kit includes all of the parts required to make the “standard” build as described in the build document, which includes switchable clipping options (which is a mod that is "built-in" to the GuitarPCB circuit, as the original commercial circuit has no switchable clipping options). If you want to create a pedal that has additional mods, we suggest that you order an undrilled enclosure and add the parts required to make this your own. If there are parts you need for mods that you don't see on our website, please contact us and we'll try our best to assist you.

All of our kits include a jack for a DC power adapter but no battery snap. Please see what is provided in a kit? in our FAQ for more details of what is included and what you will need to provide to complete the project.

    This pedal sounds awesome! The mods are easy to do and the part labeling makes assembling the kit very easy. Awesome service via email!
