GAMMA Atlas Boost Overdrive
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.
