Keeley Mk3 Driver Andy Timmons Full-Range Overdrive Pedal

Get the roaring tone of Andy Timmons with this signature overdrive pedal, a versatile unit featuring JFET saturation and true-bypass switching.

Your eyes do not deceive you, this incredible overdrive used to go by another playful and ponderous Bard-esque name! Now, the Mk3 Driver - Andy Timmons Full Range Overdrive is an overdrive workstation that allows you to orchestrate everything from a clean boost to a treble supercharger, a chimey 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 and Andy developed these switches to give players a broad range of drive tones. The Drive toggle engages two germanium diodes for a smoother, slightly compressed drive. Switch to Andy's clipping style for a brighter and more articulate attack.

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. This professional grade overdrive can be switched between true-bypass and buffered bypass at any time.

Andy Timmons - Tone Switch
The Mk3 Driver gives you two tone control circuits to choose from. When the Tone Switch is up and 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. If the Tone Switch is down and in the RK Position that features the legendary Phat Boost providing more low-end frequency response, perfect for pushing up vintage or read more single coil pickups.

Full Range Overdrive - Germanium Toggle Switch
The Mk3 Driver circuit combines JFET saturation, diode clipping, and op-amp clipping in order to create its harmonically rich tone. Drive Switch UP for AT Clipping - this mode features asymmetrical LED diode clipping and is Andy's Super AT Mod sound. Drive Switch Down for RK Clipping - now the circuit features two germanium diodes for clipping. This mode can sound a bit like a vintage fuzz pedal with a softer, smoother feel.

Mk3 Driver - Buffered Bypass or True Bypass
The Mk3 Driver features Keeley's industry-leading buffer for noise-free switching. Keeley has developed a buffer which not only makes your rig sound better, it gives you silent switching with no tone loss. Switch between true-bypass and buffered on the fly. Simply press and hold the foot switch for two seconds and the pedal will switch between true-bypass and buffered bypass! You decide what works best in your rig.
