The new Andy Timmons full range overdrive!

The MK3 Driver is an overdrive workstation that allows you to orchestrate everything from a clean boost to a treble supercharger.

Go from a chimney tube amp overdrive to a square wave, germanium fuzz generator, and more!

The MK3 Driver combines a three-control Blues Driver circuit with two switches for the voicing of Drive and Tone characteristics.

Robert Keeley and Andy Timmons developed these switches to give players a broad range of drive tones.

Set the Drive switch up for AT clipping: this mode is Andy’s Super AT Mod sound, offering a bright and more articulate attack.

Setting the Drive switch down for RK clipping engages two germanium diodes for a smoother, slightly compressed drive which can sound a bit like a vintage fuzz pedal with a softer, smoother feel.

In the AT position, the Tone control features Andy’s preferred voicing and low-end response. Each note in a chord is clear and articulate.

The RK position features the legendary Phat Boost providing a more low-end frequency response, perfect for pushing single coil pickups.

Every part of the circuit has been optimized for tone and the demanding needs of a recording and touring artist such as Andy Timmons.

Simply adding the MK3 Driver to your pedalboard will make your rig sound better!
