Keeley Electronics Mk3 Driver

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 of the low-end response of a drive pedal. 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 in the low-end frequency response, perfect for pushing 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. When the Drive Switch is Down for RK Clipping – 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 – Both Buffered Bypass & True-Bypass

The Mk3 Driver features our precise buffer for noise-free switching. We have 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 down the foot switch for two seconds and the pedal will switch between true-bypass and buffered bypass! You can decide what works best in your rig.
