51-Filthy
The Airis Effects 51-Filthy is a high-gain preamp and distortion pedal engineered to deliver the aggressive, heavy tones characteristic of modern metal. It is designed to capture a sonic blend of two iconic high-gain amplifiers: the block letter Peavey 5150 and the Diezel Hagen. The pedal functions effectively as both a distortion pedal and a preamp, offering a focused, searing high-gain sound that cuts through a mix without excessive fizz. It features a simple five-control layout: Volume, Gain, Bass, Mids, and Treble. The "Mid" control, often referred to as a "shape control," is highly versatile, allowing users to dial in a wide spectrum of tones. These range from scooped 90s solid-state sounds to the upper-mid presence of a 5150 or the warmth of an older Marshall. The 51-Filthy is praised for its tonal flexibility and ability to provide a powerful, studio-grade high-gain sound in a pedalboard-friendly format.
