Bumblebee compressor + swell files

Bumblebee compressor + swell files


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


Create ambient textures and unique effects with the BUMBLEBEE, a combination swell & compressor pedal. Wide attack & decay ranges yield bowed guitar, reverse delay, and slow, synth pad-style effects. Blend it with the optical compressor for a unique “blooming” effect, or isolate the  compressor & use it to tighten up your tone. Combine with a delay or reverb pedal for a taste of sonic heaven. The BUMBLEBEE loves bass too!


These files are for personal use only. If you want to build & sell the Bumblebee 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
