This is a library of perfboard and single-sided PCB effect layouts for guitar and bass. I'm not an electrical engineer by any stretch of the imagination, just a DIY'er who likes drawing layouts. It is meant for the hobbyist (so commercial use of any of these layout is not allowed without permission) and as a way to give back to the online DIY community.

Majik Box Rocket Fuel

Got a request for this one on the Facebook page. The original Rocket Fuel is an overdrive and a boost in one 1590BB enclosure. The overdrive side is essentially a Tube Screamer without any diodes, and the boost section is a straight MXR MicroAmp clone. The overdrive side is below and is laid it out for 9mm mini pots you can mount directly to the board from the solder side. If you build it without the boost daughter board, you can fit it in a 1590B.

There's also 3-position switch for changing the bass response. Use a DPDT on/off/on and wire it like this:


  1. Great layout but where is the switch for the booster that exists in the original? Tanks!!

    1. The boost is a separate circuit–the MicroAmp. You'd wire it like you would an independent pedal.


    2. you possesses the electric scheme , you can give me ? Great tanks!

    3. Here's the schem of the overdrive portion:

      The boost is the same as the MXR MicroAmp

  2. Great job as always. Many thanks

  3. Hola estimado. Cual es el reemplazo del OPA2604. Saludos
