Used GAMMA ATLAS Effect Pedal

The GAMMA Atlas Boosted Overdrive provides three of the typical control knobs (Level, Tone and Drive), but adds a secret sonic weapon—a Boosted/Normal switch. This feature isn’t merely a conventional level boost for hitting your amp’s front end harder or adding a soaring volume increase. While there is a slight level surge when Boosted is engaged, the switch is actually a tonal enhancement that simultaneously lifts up the low-and high-midrange frequencies, allowing players to bring on a warm, vintage crunch (Normal) or fire off some modern rock savagery (Boosted).
