*REGULAR PRICE is $2000 CAD*

Hi, my name is Mitch and I run a small company called MDC (Mitch Davis Circuits)

I've been a touring/session musician as well as a repair tech for well over 10 years, through which I have gotten to know a massive variety of pro audio equipment from all eras.

This is my first major product of my own design. It has been a labour of love and obsession and I've spent the last number of years refining and perfecting the circuit. I can confidently say it's an incredible tool for tracking, mixing, and even mastering.

It can be extremely clean and transparent, with excellent THD and noise floor performance. But, it can also be an amazing distortion box when you want it to be. I love to hit that line a bit when tracking bass or vocals. I apologize for the small number of audio demos, but it's something I am working on and I will update the folder as I do.

I have parts on hand for 7 units before I launch a wider kickstarter campaign.

37 units sold, at various stages of development.
