The Carl Martin AC-Tone Single is a scaled-down (though not exactly scaled-back) version of the dual channel Pro Series AC-Tone, with top-boosted Vox tones in a tidy metal enclosure. Three simple controls for drive, output level, and high-frequency cut mimic the cutting drive tones of vintage AC-series British amps with the same high-quality components as the bigger AC-Tone dual channel pedal.
