Used Browne Amplification Protein V4 Dual Overdrive

A highly regarded dual overdrive pedal designed for versatile, amp-like drive tones. The Protein V4 combines two independent circuits—the smooth, low-gain “Blue” side and the fuller, mid-gain “Green” side—each excellent on its own and even more powerful when stacked together for thicker, harmonically rich drive. The Blue side offers articulate breakup and boost-style clarity, while the Green side adds warmth, punch, and added saturation for leads or heavier rhythm work.

Version 4 adds expanded tonal control, including a 3-way hi-cut switch and additional internal clipping and low-end options, making it easy to tailor the pedal to different guitars and amps. Dynamic, flexible, and pedalboard-friendly, the Protein V4 has become a go-to overdrive for players who want multiple gain stages in a single compact unit.
