The Mk3 Driver – Andy Timmons Full Range Overdrive pedal is a dedicated overdrive workstation, allowing you to create a multitude of sounds, from clean boosts and treble saturation to crystal-clear tube amp overdrive, a germanium square-wave fuzz generator, and much more. This pedal combines a three-control blues driver circuit with two switches for Drive and Tone characteristics. Robert and Andy developed these switches to offer musicians a wide range of saturated tones. The Drive switch activates two germanium diodes for a smoother, slightly compressed drive. Opt for Andy's clipping style for a brighter, more articulate attack. Every element of the circuit has been optimized for the sound and demands of a studio and touring artist like Andy Timmons. Adding the Mk3 Driver to your pedalboard will likely improve the sound of your setup. This professional-sounding overdrive can be switched between true-bypass and buffered bypass at any time.

Classic blues saturation circuit, the result of decades of Keeley experience in modifications.

Germanium-based overdrive designed under the direction of Andy Timmons.

AT/RK Tone Switch: Cuts the bass for clarity or boosts it for more power.

AT/RK Gain Switch: Switches between single silicon diodes and dual germanium diodes.

Buffered Bypass or True-Bypass: Instantly switch to suit your setup.

JFET transistors, germanium diodes, and op-amp gain combine to create harmonically rich saturation.

Operates from 9 to 18 volts for exceptional dynamics and headroom.

ANDY TIMMONS – TONE SWITCH

The Driver Mk3 offers two tone control circuits. When the tone selector is in the AT position, the tone control delivers Andy's preferred low-end response for an overdrive pedal. Every note in a chord is clear and articulate. If the tone selector is in the RK position, you get the legendary Phat Boost in the low frequencies, ideal for boosting vintage or single-coil pickups.

FULL RANGE OVERDRIVE – SLIDESHOW SWITCH

The Mk3 Driver circuit combines JFET saturation, diode clipping, and op-amp clipping to create a harmonically rich tone. Drive selector in the up position for AT clipping: this mode uses asymmetrical LED clipping and delivers Andy's Super AT Mod sound. Drive selector in the down position for RK clipping: the circuit uses two germanium diodes for clipping. This mode can sound like a vintage fuzz pedal, with a softer, smoother feel.

MK3 DRIVER – BUFFERED BYPASS AND TRUE-BYPASS

The Mk3 Driver features our precision buffer for noise-free switching. We developed a buffer that not only enhances the sound of your setup but also provides silent switching without any loss of tone. Instantly switch from true-bypass to buffered mode. Simply hold the pedal down for two seconds to toggle between the two modes! Choose the perfect setup for your gear.

MADE IN THE USA – MK3 DRIVER – ANDY TIMMONS FULL-RANGE OVERDRIVE

We design, develop, and manufacture the Keeley Electronics/Andy Timmons Mk3 Driver pedal in Oklahoma City. Everything about the Mk3 Driver is designed for the professional musician and their quest for an inspiring sound, even on stage. From the pedal's meticulously designed circuit boards to its newly manufactured aluminum enclosure, we create guitar effects pedals that are true musical instruments.

A word from Andy Timmons:

The Mk3 Driver is the ultimate expression of the slightly overdriven clean tone I've been searching for for years. Robert Keeley and his fantastic team have once again delivered an exceptional job! The AT/AT setting is exactly what I love about my Super AT Mod: just the right amount of saturation, endlessly customizable. Every note, every nuance, is crystal clear. The craziest thing is that this mode also sounds amazing with the gain cranked, delivering an incredibly cool Marshall crunch.

Owning the RK-modified BD-2 circuit is a real luxury, because it's the one I fell in love with years ago! It still inspires me just as much!

The real hidden gem is Robert's new modification, which uses germanium diodes instead of the original silicon ones. This results in a new type of clipping that works wonderfully, either on its own or as a boost for my solos. It allows me to tame the bass with a precision I absolutely love.

With the Mk3 Driver and the Halo, I'm in sonic heaven!
