The Carl Martin AC Tone is a focused, British-style overdrive pedal that delivers a dynamic, touch-responsive feel in a compact, single-channel design built for modern pedalboards. A unique Cut control acts as a low-pass filter, allowing you to tame the high-end without dulling your overall tone. Featuring simple, intuitive Level, Drive, and Cut controls for straightforward sound shaping, the pedal runs internally at ±12V via a standard 9V supply to ensure extra headroom and maximum clarity.

When Carl Martin set out to make AC-Tone Single, the idea wasn’t to simplify the sound — it was to make it more focused. This pedal carries the same core voice as its bigger sibling, the Pro Series AC-Tone, but in a single-channel format that fits naturally into modern pedalboards.

The Carl Martin design team kept the character intact and pushed the overdrive section a bit further, giving it more authority when you lean into it. From open, chiming cleans to saturated British-style drive, the feel stays dynamic and touch-responsive throughout. The goal was always to let your playing control how far things go.

A key part of that is the Cut control. Rather than shaping the entire EQ, it works like a low-pass filter, allowing you to tame high-end content without flattening the tone. It’s especially useful when switching guitars, amps, or speakers — or when a sound that works at home suddenly feels too sharp on stage.

Despite its compact size, AC-Tone Single isn’t a compromise. Under the hood, we use our DC-DC converter circuitry, allowing the pedal to run from a regulated 9V supply while internally operating at ±12V — just like the original AC-powered AC-Tone. That extra headroom is a big part of why the pedal stays articulate and controlled, even at higher drive settings.

It’s a straightforward design, built around Level, Drive, and Cut — and that’s very much the point. Everything you need is right there, ready to respond when you play.
