Browne Protein V4 – Same Soul. More Control. All Tone.
The Protein V4 takes everything players loved about the original Protein—and adds even more tonal control and flexibility to meet the needs of modern stage and studio rigs.
Born from a collaboration between David Brown and guitarist/producer Adam Sniegowski, the Protein was designed to solve a simple but critical problem: how to get a consistently great overdrive sound, no matter the amp or backline.
Inspired by the legendary BluesBreaker-style circuit heard on albums like Continuum, the Protein's Blue side delivers warm, open overdrive with excellent touch sensitivity. For V4, Browne refined the tone circuit, boosted the available output, and crafted what many consider their favorite version of this classic tone—true to the original, but undeniably improved.
The Green side is based on the iconic Nashville overdrive favored by top session players like Tim Pierce and Jerry McPherson. In V4, the gain has been revoiced for a smoother sweep, the mids reshaped for added presence, and the low end tightened to eliminate mud. The result? A rich, punchy drive that adds low-mid weight without sacrificing clarity.
Running the Green into the Blue unlocks a harmonically rich, high-headroom third “channel” with extra gain and girth—perfect for lead tones or saturated rhythm parts. The stacked sound is full and articulate, without the mushiness that plagues many dual overdrives.
Whether you're chasing smooth breakup, Nashville clarity, or stacked lead tones, the Protein V4 delivers with stunning consistency—on any stage, in any mix!
What’s New in V4:
• A 3-way Hi-Cut toggle (from the Carbon V2) to fine-tune the Blue side’s top end
• Three internal Green-side switches for even more flexibility:
– Low Cut: Tightens up the low end
– Heavy Clipping Mode: Adds bite and breakup
– Asymmetrical Clipping: Introduces harmonic complexity and a rawer edge
