The Browne Amplification Protein V4: Dual Overdrive that Defines Modern Stacking Tone

Dual Overdrive Pedal with Studio Born Versatility

The Browne Amplification Protein V4 is a purpose built dual overdrive designed to solve a real world problem. Inconsistent backline amps can derail even the best players, so this circuit was developed to deliver reliable, musical drive tones in any environment. Built from two carefully refined overdrive circuits, the Protein V4 preserves the soul of classic tones while addressing their limitations. The result is a pedal that feels immediately familiar yet unmistakably elevated.

Blue Side Overdrive with Headroom and Clarity

The Blue side delivers a lower gain overdrive with substantial headroom and a surprising amount of output. It responds dynamically to your playing, adding brightness and harmonic detail as the gain increases. The active tone control interacts closely with the gain structure, allowing you to shape everything from smooth breakup to articulate edge of drive tones. A three way hi cut switch provides precise control over the top end, making it easy to tailor the response to different rigs and guitars.

Green Side Overdrive with Midrange Focus and Punch

On the opposite side, the Green channel brings a slightly higher gain voice with enhanced midrange and a touch of compression. This side is tuned to sit perfectly in a mix, offering punchy rhythm tones and singing lead sustain without losing definition. The gain structure has been refined to remain usable across the full sweep of the control, avoiding muddiness while adding low mid presence and body.

Stacking Capability and the Secret Third Channel

Where the Protein V4 truly shines is in its stacking performance. Running the Green side into the Blue creates a rich, full gain structure that maintains clarity and avoids the mushiness common in stacked drives. This “third channel” expands the pedal into a highly flexible gain platform, capable of everything from subtle boost to saturated lead tones while retaining note separation and articulation.

Advanced Tone Shaping and Internal Controls

Beyond the external controls, the Protein V4 includes internal switches that unlock deeper tonal shaping. Options such as additional clipping modes, asymmetrical clipping, and low cut adjustments allow you to fine tune the response, gain character, and low end behavior to suit your rig. Combined with standard 9V DC operation and thoughtful control layout, this pedal is built for players who demand precision and flexibility from their drive section.
