Your eyes are not deceiving you! This incredible overdrive used to go by another name. The new 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.

Combines JFET saturation, diode clipping, and op-amp clipping for a harmonically rich tone.

Key Features

  • Three-Control Blues Driver – This pedal combines a three-control blues driver circuit with two switches for the voicing of Drive and Tone characteristics.
  • True of Buffered Bypass? – This professional grade overdrive can be switched between true-bypass and buffered bypass at any time.
  • 9-18v Operation – Huge dynamic range and headroom.

Robert Keeley and Andy Timmons 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.

Drive Switch

AT: Asymmetrical LED and silicon diode clipping

RK: Dual germanium diodes – softer, smoother feel with almost fuzzy characteristics

Selectable Buffered/True Bypass Switching – Change instantly and on-the-fly depending on your rig’s needs

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

This pedal’s 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 and silicon diode clipping and is Andy’s Super AT Mod sound.

A Note From Andy Timmons

‘The Mk3 Driver is the ultimate expression of the clean/slightly broken-up tone I’ve been going for over the last several years. Robert Keeley and his incredible team have once again knocked it out of the park!

The AT/AT setting is exactly my Super AT Mod tone: just the right amount of breakup available at your dynamic command. Every note and nuance is clear as a bell. The crazy thing about this mode is that it also sounds great with the gain turned up, providing an incredibly cool Marshall-esque crunch tone.

Having the original RK modded BD-2 circuit is sheer luxury as that’s the circuit that I fell in love with years ago! It still inspires me!

The real hidden gem here is Robert’s new modification that utilizes germanium diodes instead of the original silicon for a new kind of clipping that works insanely well on its own OR as a boost for my lead tone. It has a lovely way of further taming the low-end that I really love.

With the Mk3 Driver and the Halo, I’m in Tone Heaven!’

Overdrive Pedals

Overdrive uses soft or moderate clipping to add harmonics and compression while retaining more of the original note shape than heavy distortion. Some circuits emphasise the midrange and trim bass before clipping; others remain broad, transparent or amplifier-like. Gain, clipping arrangement, headroom and tone filtering decide whether it supplies a light edge, a saturated drive sound or extra push into another gain stage.

Buffered Bypass

Keeps an active buffer in the signal path when the effect is bypassed. The buffer converts a high-impedance input to a lower-impedance output, helping long cables and multiple pedals retain level and high frequencies, although its headroom and noise remain part of the path.

True Bypass

Connects input directly to output through mechanical or relay switching when the effect is off, removing the active circuit from the audio path. It avoids buffer colour but leaves cable capacitance and switching design to influence high-frequency loss and possible switching noise.
