OWNER’S MANUAL

Your GAMMA SERIES Atlas Boosted Overdrive from Acoustic Control Corporation allows you to add nuanced, tube ampstyle overdrive to your guitar sound, with a Boost switch that pushes low frequencies and adds more high end bite to the drive sound. This distortion preserves your dynamics and articulation, and is nicely responsive to volume, tone and pickup adjustments you make on your guitar. It’s all built into a road-ready metal chassis with metal knobs, operating from either a 9-volt battery, or 9-volt DC power supply.

    You can power your GAMMA Series pedal from a 9-volt regulated DC adapter (plug polarity is positive on the barrel and negative in the center).

  2. Battery Capability
    Use a Phillips head screwdriver to remove 4 bottom screws to access battery connection. High quality alkaline 9-volt battery can be used for approximately 50 hours of continual operation.

    Boost setting adds low frequency energy, and adds more high end bite to the DRIVE.
