Update: The parts needed for this project arrived and the pcb is populated and ready to test. The ssm2166 adapter is mounted in the socket on the right.
What makes this buffer board special is that the input has been designed to duplicate the input circuitry of the typical tube amp, and it thereby preserves the interaction between the guitar’s pickups and the buffer circuit. This makes the sound of the guitar more natural, with a similar resonant peak, while still providing a low impedance output drive for your cables and pedalboard.

I have added instructions to the relay bypass support page to show how to use it as an A/B box controller. Also added are instructions on using the relay board to switch the booster/buffer outputs of the AMZ Mosfet Booster

The Big Muff may be a classic distortion design, but it is often too much of a good thing. The cascaded gain stages with the dual diode clipping will remove most of the dynamic range from the sound. This article is about trimming down the basic design to give back some of the dynamics, enhance transparency and make the pedal a more useful and versatile distortion/overdrive.
My metal box finishing tutorial (with over 38,000 views) has been posted on the front page of the Instructables site as a “featured” project:
There is now a Support Forum for the projects based on the AMZ circuit boards. You can ask questions and request additional info by posting in the forum. Thanks!

I have had the opportunity to play the Empress Compressor for a couple of weeks and would like to share some of my findings. The image above shows the Empress Compressor on the left and Dunlop compressor on the right that I used for my initial comparisons. Both are true bypass.
The Electro-Harmonix 9 volt battery is the classic carbon zinc composition.
