A Keeley Modded Blues Driver is nothing short of special. There’s something even more remarkable about Andy Timmons’ tone. As his exposure to this Keeley modded stompbox early on, it has been a permanent fixture to Andy’s board. The Super AT Mod Overdrive captures the magic of the original Blues Driver Phat Mod with the addition of AT Mode. Chord work and harmonies are cleaner and tighter without loss of gain.

The new Super AT Mod Overdrive features a return to RK's original clipping style, a 20 year old modification first found in the Keeley Blues Driver Phat Mod. If you're after a drive pedal that responds just like a tube amp, look no further.

The topology of the pedal is similar to classic California tube amps, we simply use JFET transistors in place of tubes. Nothing has been left out, even the filtering of an amp's tone stack is designed into the pedal. It's an amp-in-a-box, but made better as it's Keeley developed with the guidance of Andy Timmons!
