Smaller pedal-board friendly, single channel version of the original Carl Martin’s Pro-Series AC-Tone overdrive effect pedal that features 3 knobs and 1 switch and has a slightly beefed up Gain section, but shares the very same tone as its big predecessor. This version also incorporates the DC-DC converter circuitry, so the pedal can be powered by a regulated 9V power supply but will still operate on the same +-12V level as the original AC powered AC-Tone. This allows for using the same high quality components which provide the same tone and headroom.
