The Carl Martin AC-Tone Single is a compact single-channel overdrive pedal. Carl Martin describes it as a "dynamic overdrive pedal delivering classic British tones with modern flexibility", aimed at a focused British-style overdrive with a dynamic, touch-responsive feel1. For players chasing the sound of a cranked British amp in a pedal, it sits in the overdrive family alongside the company's other drive pedals such as the PlexiTone and the DC Drive.
One channel instead of two
The Single is a one-channel version of the dual-channel Pro Series AC-Tone, as Carl Martin explains in its own support material2. Where the two-channel pedal carries a second channel and the switching that goes with it, the Single keeps one drive channel in a smaller footprint. Carl Martin describes the design as compact and easy to fit on a modern pedalboard1, which is the practical difference for players building a board around a single drive sound rather than switching between two.
Carl Martin lists the AC-Tone Single at 149,00 EUR on its European product pages3 and at $199.00 in US dollars on the product page for this pedal1. The two figures are quoted in different currencies as stated by the maker.
