Brandishing the potent strength of mythological Greek titan Atlas—who bore the entire universe on his shoulders—the GAMMA Atlas Boosted Overdrive has the power to elevate your guitar tone from a stout growl to a resounding roar. Created to produce fat, tube-amp-inspired grind, Atlas is one of six stompboxes in our exclusive GAMMA guitar effects pedals line—which also includes the Bacchus Dynamic Driver, Cumulus 3-Way Reverb, Eros Clean Chorus, Hades Metal Distortion and Narcissus Warm Delay. We’re Guitar Center, and we know guitar players, so we populated the GAMMA line with six effects that are absolutely essential for gigging. In fact, you can construct a versatile and professional pedalboard with the sextet of GAMMA pedals alone.
All pedals in the GAMMA guitar effects series feature stunning metal-flake finishes, gig-resilient chassis and knobs, scrupulously curated circuitry and buffered bypass (for consistent tone and signal output), as well as a compact size that won’t devour real estate on your pedalboard. Each GAMMA pedal can be run from a 9-volt battery or power supply (battery and DC adapter not included). In addition, we are extremely aware that the last thing players want is for their gear to crumble under pressure, so the GAMMA line was designed to defy the rigors of constant use and to sound sensational every time you plug in to play.
