One of the best dual-overdrives on the market just got better! The Browne Protein v4 packs two classic overdrive textures in one, with a powerful control set that keeps things simple, making dialing in your sound quick and effortless.

At its core, the Protein features a green side voiced after the famous "Nashville" session overdrive, with that mid-hump focus and plenty of saturation. On the left you'll enjoy the Carbon circuit, a modified Bluesbreaker that works wonderfully for light overdrive, stacked clean boost purposes and more!

What's new with Version 4?

The Protein V4 introduces several key updates for even more versatility and tonal control:

A 3-way hi-cut toggle, taken from our Carbon V2, allows you to tailor the top end to your amp or preferences
Three internal switches on the Green side:
Low cut toggle for tightening the low end even more
A heavier clipping mode for a more aggressive breakup
An asymmetrical clipping option for added harmonic complexity and a slightly rawer edge
These additions make the Protein more adaptable than ever—whether you're chasing Nashville clarity, smooth breakup, or a harmonically rich lead tone, the V4 is built for your pedal board needs.
