Browne Amplification Protein V4 Dual Overdrive Pedal, Green

Browne Amplification Protein Dual Overdrive V4 Guitar Pedal

The Protein Dual Overdrive V4 is a dual overdrive guitar pedal with a Blue side, a Green side, and a stacked mode that runs the Green into the Blue. It was developed by David Brown with guitarist and producer Adam Sniegowski, who wanted a dual overdrive that sounds good whichever backline amp it is plugged into. The design started from two overdrives that stacked well but had quirks, and the goal was to fix those quirks while keeping the character of the originals. The Blue side draws on the overdrive heard on John Mayer’s “Continuum”, and the Green side on the Nashville overdrive used by session players like Tim Pierce and Jerry McPherson.

Frequently Asked Questions

What is the difference between the Blue and Green sides?

The Blue side is a transparent, very dynamic modification of the most famous "blue" circuit. Tone control and Volume are more usable and the circuit has more output. The Green side is inspired by the classic green Nashville overdrive used by session players. It has lower gain, fuller mids, and a tighter low end for a warm, creamy, punchy drive that adds low-mid weight without getting muddy.

What is stacked mode?

Stacked mode runs the Green side into the Blue side. It works as a third channel with more gain and fullness, and it is designed to keep notes clear instead of turning mushy.

What is new in V4?

V4 adds a 3-way hi-cut toggle taken from the Carbon V2, plus three internal switches on the Green side: a low cut toggle, a heavier clipping mode, and an asymmetrical clipping option.

Can I adjust the top end for my amp?

Yes. The 3-way hi-cut toggle lets you tailor the high frequencies to your amp or your preference.

Are the Green side switches on the outside of the pedal?

No. The low cut, heavier clipping, and asymmetrical clipping options are internal switches.

Who designed it?

David Brown developed it together with guitarist and producer Adam Sniegowski.
