Keeley Limited Edition Super AT Mod Andy Timmons Overdrive

There is something special about a Keeley Modded Blues Driver. There’s something even more remarkable about Andy Timmons’ tone. Coincidence? We think not. Since his exposure to this Keeley modded stompbox early on, it has been virtually glued 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 now, without reducing gain.

Asymmetrical Tube Clipping

The new Super AT Mod Overdrive features a return to RK's original clipping style, a 20 year old modification first performed in the Keeley Blues Driver Phat Mod. If you want a drive pedal that responds just like a tube amp, this is it. 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, only better because it's Keeley developed with the guidance of Andy Timmons!

New Tone Switch

There is a new circuit design for the Tone Switch employed in the Super AT Mod. The new AT-mode is voiced for humbuckers and features lower mid-bass frequencies for tighter, more transparent response. The original Keeley PHAT-mode stands ready to put more power behind your favorite single coil equipped guitar. Either way, the Super AT Mod has got you covered.

"The Super AT Mod Overdrive is the ultimate expression of the slightly broken up/clean tone I have been searching for all these years. It also rocks with an amazing overdrive tone that is incredibly amp-like. I already have 2 on my board! Wishing you all the best on your Tone Quest!" - Andy Timmons
