ProCo

Description

Reborn from one of the most iconic distortion circuits ever made, the ProCo Sterling Vermin RAT distortion pedal takes the legendary RAT formula and sharpens it for a new generation of players. Hand-soldered in small batches in Jackson, Missouri, this refined take on the classic delivers the same snarling attitude and midrange bite that defined countless records—now with expanded tonal control and boutique-grade precision. At its heart, the LM741 op-amp and selectable clipping diodes let you flip between the classic silicon RAT grind and the smoother, more articulate voice of BAT41 diodes. The result is a distortion pedal that roars when pushed, purrs when restrained, and responds beautifully to your playing dynamics. With premium CTS pots, oversized glow-in-the-dark knobs, and both true or buffered bypass modes, the Sterling Vermin feels as solid and expressive as it sounds—built to inspire, endure, and redefine what a modern RAT can be.

Selectable Diodes for Ultimate Tonal Flexibility

The ProCo Sterling Vermin offers two clipping diode options: the traditional silicon diodes from the original RAT and BAT41 diodes for a smoother, more balanced tone. A simple toggle switch allows you to seamlessly shift between punchy, cutting midrange tones or a more rounded, versatile overdrive. This feature ensures you're equipped to achieve everything from gritty distortion to subtle, dynamic sounds, making the pedal adaptable to diverse playing styles and genres.

Premium Components for Precise Control

Built with high-quality CTS pots and oversized knobs, the ProCo Sterling Vermin guarantees smooth, responsive control with just the right amount of resistance for precision. Whether adjusting the gain, tone, or volume, these top-tier components allow you to fine-tune your sound with confidence. The result is a distortion pedal that feels as good to use as it sounds, giving you unmatched playability and tonal versatility.

Enhanced Usability for Modern Players

The Sterling Vermin RAT pedal features an intuitive layout that helps players focus on their music. Glow-in-the-dark pointers on the oversized knobs make on-stage adjustments effortless, even in dim lighting. Additionally, the pedal includes an internal switch for choosing between true bypass, for uncolored tone, or buffered bypass, to maintain high-frequency clarity with longer cable setups. A remote control option for the gain boost feature provides even more flexibility for live performances, ensuring seamless operation for any gig.

Polished Design and Durable Construction

The ProCo Sterling Vermin is built to last with its polished stainless-steel enclosure and rugged design. Hand-assembled in Jackson, Missouri, the pedal combines sturdy build quality with striking aesthetics, including laser-etched graphics that add a modern touch to its vintage-inspired design. With top-loading battery access and reliable components, this pedal is engineered for years of consistent performance, whether in the studio or on stage.
