Klein Bottle looper-mixer design files
This item provides a digital download of a ZIP file with all the documentation needed to build the Klein Bottle.
The Klein Bottle was designed for the noise makers, soundscape artists, endless tinkerers and tone wizards. This epic pedal starts by splitting the input signal into three FX loops, each with dedicated controls for pre-gain, HPF/LPF (bandwidth filters), and mix level. The magic happens when you use the six feedback controls to send the signal from one FX loop into another...and then back again! Keep your existing tone intact with the DRY knob, while layering a cornucopia of sonic goodness on top.
These files are for personal use only. If you want to build & sell the Alpha Dog 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 https://www.vfepedals.com/graphics.
