Browne Amplification Limited Edition The Protein V4 Dual Overdrive Pedal in Gold

The Browne Amplification Limited Edition Protein V4 Dual Overdrive in Gold is a studio-grade, two-channel drive pedal designed to sound inspiring into virtually any amp. Co-created by David Brown and guitarist/producer Adam Sniegowski, it takes two much-loved classic overdrives, refines their quirks, and combines them into a flexible, stackable tone machine that excels at everything from Nashville sparkle to smooth, singing leads.

On its own, each side delivers a familiar yet improved flavour of drive. Together, they create a powerful third channel that stays clear, punchy and articulate, even at higher gain settings. With the addition of a three-way hi-cut switch and internal voicing options on the Green side, the Protein V4 offers a level of control that makes it easy to dial in your sound for any guitar, amp or session.

This limited edition Gold finish adds a touch of class to your pedalboard, but it is the sound and versatility that will keep you stepping on it night after night. Whether you are a touring pro dealing with unpredictable backline rigs or a home player chasing record-ready tones at sensible volumes, the Protein V4 is built to deliver consistent, musical overdrive in every situation.

Refined Blue Side Overdrive

The Blue side is based on the iconic overdrive heard on countless modern blues and pop records, including John Mayer’s Continuum era. Browne have addressed the limitations of the original by increasing the available output, revoicing the tone control for a more usable sweep, and subtly refining the circuit. The result is a smooth, touch-sensitive drive that retains the character players love, but with more headroom, clarity and control, making it ideal for edge-of-breakup rhythm work or fluid lead tones.

Improved Nashville-style Green Side

Inspired by the classic Nashville session overdrive favoured by players like Tim Pierce and Jerry McPherson, the Green side has been carefully tweaked for real-world usability. The gain range has been reduced for a more controlled sweep, the midrange has been rebalanced for a fuller presence, and the low end tightened to remove unwanted woofiness. This gives you a warm, punchy drive that adds low-mid weight and authority without turning muddy, perfect for country, rock and worship styles alike.

Powerful Stacked Mode

Running the Green side into the Blue unlocks the Protein’s celebrated stacked mode, effectively giving you a third channel. This configuration adds gain, sustain and fullness while preserving note separation and avoiding the mushiness that often plagues stacked overdrives. Chords stay defined, single notes cut through the mix, and your picking dynamics remain intact, making it an excellent option for solos, big choruses or heavier textures without losing musicality.

V4 Versatility and Tone Shaping

The V4 update introduces a three-way hi-cut toggle, borrowed from Browne’s Carbon V2, allowing you to fine-tune the top end to suit brighter or darker amps. On the Green side, three internal switches provide even deeper control: a low cut option for an even tighter bottom end, a heavier clipping mode for more aggressive saturation, and an asymmetrical clipping setting for added harmonic complexity and a slightly rawer edge. Together, these features make the Protein V4 adaptable to almost any rig or genre, from subtle tone sweetening to harmonically rich lead work.

• Dual Refined Classic Overdrives - The Protein V4 combines two beloved overdrive voices in one compact enclosure, each carefully refined to fix the quirks of the originals while preserving their core character. This gives you familiar, record-ready tones with improved headroom, clarity and control, reducing the need for multiple single-drive pedals.
• Musical Stacked Third Channel - Engaging both sides in series creates a powerful stacked mode that functions like a third channel. You get increased gain and sustain without the flubby low end or smeared mids that can occur when stacking other drives, making it ideal for solos and big dynamic moments where you need more intensity but still want definition.
• V4 Hi-cut and Internal Voicing Options - The three-way hi-cut toggle lets you quickly tailor the top end to suit bright single-coils, darker humbuckers or different amps. Internal low cut and clipping switches on the Green side offer even more fine-tuning, so you can dial in anything from tight, articulate rhythm crunch to harmonically rich, slightly ragged lead tones.
• Consistent Tone with Any Backline - Designed specifically to sound great into a wide range of amps, the Protein V4 helps you achieve consistent, professional-quality overdrive whether you are using your own rig or relying on whatever is available on the day. This makes it a dependable core drive solution for touring players, session musicians and gigging guitarists who cannot always control the backline.
