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 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.
