Stage 3 Booster Kit

This kit includes all of the parts needed to build the GuitarPCB Stage 3 Booster project. Based on a Fetzer Valve boost, this version uses particular components and values to give you an incredible tone enhancement. We consider this more of a tone boost than a solo boost, but the circuit includes an on-board trimmer potentiometer which can be adjusted to give a higher-gain overdrive sound. This is the board which made a huge hit, and remains a top seller even several years after it was released. Due to the low-part count of this circuit, this is a perfect starting place for someone building their first pedal.


This kit includes a 1590B enclosure and black aluminum knobs.


All of our kits include a jack for a DC power adapter but no battery snap. If you wish to add a battery snap, please add a battery snap kit to your cart in addition to the pedal kit. 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.
