Deluge Bass Distortion
The Deluge is a great sounding bass distortion by J. Michael Pedals. This is based on the Big Muff™ distortion, but tuned for bass. It is built on our BMP PCB and when you buy the kit the kit bag will be a BMP kit bag with the small parts bag labeled "Deluge" .

This is the Deluge Bass Distortion. Use the project documents provided, starting with the General Build Instructions. See special instructions on how to install FET transistors as clippers in the “Technical Help” “Building Kits” pages.
Here's an inside view of the unit we built to give you some general ideas if needed.
Here is a chart of voltages taken at the transistor pins. This information can be used to help you find and fix problems if your BMP doesn't work when you test it.

Deluge Sound Sample:
Ready to build? We have the kit.
Buy an Deluge Complete Kit. Includes all the parts and materials you need to build one, all for about the price you would pay for a PCB and parts.
Would you like a Ready to Solder Circuit Board for this project? Note: If you buy the kit, the Ready-to-Solder Printed Circuit Board (RTS PCB) is included in the kit. You do not need to purchase this Ready to Solder Circuit Printed Board if you buy the kit.
