Dragon dynamic overdrive + boost files


This item provides a digital download of a ZIP file with all the documentation needed to build the Dragon.


Tubescreamer. Rat. Klon. OCD. Tim. KoT. What do all these beloved drive circuits have in common? They all cut bass before distortion, and cut treble after distortion. This basic recipe is the backbone of many of the dirt pedals you use. Enter the Dragon, a dynamic overdrive designed to give you ultimate power over the pre-gain bass cut (HPF) and post-gain treble cut (LPF). Precisely tighten or fatten up your low end, smooth out the top end or add sparkle. Go from a transparent tone to a focused mid boost to push through a dense band mix, or just use it to light your favorite drive on fire.


These files are for personal use only. If you want to build & sell the Dragon as a commercial product, you can become an authorized VFE builder.


I recommend that you create an account in order to easily re-download these design files later, especially when I update them.

  • Included Files

    Here is a full list of included files:

    README - Outlines the basic organization of the files within the ZIP file. It also contains links to multiple YouTube videos that will help you build the pedal and understand how it works, plus information about the various versions of the pedal.

    SCHEMATICS - Contains schematics of every version of the circuit, categorized by series (SPS, Standard, Live).

    EAGLE FILES - Contains all the Eagle files from the different versions of the pedal. Earlier versions may be a bit messy to work with, but are included to help with repair or mod work on discontinued versions of the pedal.

    GERBER FILES - These ZIP files contain everything you need to get the latest version of the PCBs fabricated. The files have been optimized for the Gerber extensions used by PCBway, so they may not work at all fabrication shops unless you change the extensions on each file.

    ASSEMBLY FILES - Contains the assembly sheets with a master parts spreadsheet for  most recent version of the pedal. When available, I've added assembly sheets for earlier versions, too.

    TEMPLATES - Contains templates for the drill holes. Free templates for the graphics can be found at
