VOL: Turn it up, volume goes up.
TONE: While AC30s offer treble and bass controls, May never cared much for the bass side. This Tone control governs the amount of treble present in the signal, making it very useful for brightening up a dark amp or post-Galileo drive pedal. The Galileo’s Tone knob also goes well beyond the boundaries of a normal AC30, providing a different flavor of Vox that stands out in any mix.

GAIN: Just like a real AC30, this controls the amount of distortion present in the signal, from the light-breakup “jangly” sound for which the clean AC30 is known to blistering leads when cranked. This control is highly interactive with your guitar’s knobs and any outboard, guitar-mounted switching you may have.
The Galileo accepts a center-negative DC power supply from 9 to 18 volts
