Move from clear, bluesy articulation to Nashville-style crunch without adding separate pedals to your board. The Browne Amplification Protein Dual Overdrive V4 pairs two distinct analog circuits in a copper-finish chassis, ready to use alone or stacked for thicker sustain with clear notes.

Use the Blue side for lower-gain headroom, then bring in Green for tighter lows and enhanced mids. Stack them for layered lead tones or to shape an amplifier’s edge-of-breakup sound.

Add two complementary drive voices to your setup in one pedal. Order the Protein V4 in copper; free shipping is available within the continental U.S. at checkout. For shipping outside the U.S., contact for a quote.

List of Features

• Two overdrive circuits: Play each side separately or combine their distinct tone shapes.
• V4 tonal options: A three-position Hi Cut switch shapes the Blue channel; Green adds internal Low Cut, More Clip, and Asymmetrical Clipping routing.
• Dedicated controls: Each circuit has its own Level, Gain/Drive, and Tone knobs for independent adjustments.
• Soft-touch footswitches: Switch either circuit with its dedicated footswitch as you play.
• TRS split mode: Internal TRS jacks route the overdrives through separate expression or loop sends for pedalboard integration.
• Board-ready build: USA-assembled, it measures 120 x 94 x 56mm and runs on a standard 9V DC center-negative adapter, drawing under 130mA.
