From the vendor

Project overview

We took each side of the amazing Protein Drive Overdrive and made two independent pedals. The Blue Side is a modernized version of the classic OD originally used by countless guitar players worldwide but perhaps most famously by John Mayer on his “Continuum” album.

Introduction

The Protein was years in development and road testing before it ever made its way into the hands of the public; each side was carefully recrafted, and that’s what makes the Blue Side so dam good. Dave Brown from Browne Amplification addressed issues of the original, like the lack of output, tweaked the tone control, and experimented to find the perfect circuit while still being true to its roots.

Protein Blue is an almost HD take on the old 1990s Marshall Bluesbreaker. It is a smooth, rich boost and low-gain overdrive with a lower-mid boost that particularly flatters vintage Strats.

You can have the classic Blue Side or Green Side as separated pedals or build the Protein Dual Overdrive and stack them together in every possible way!
