Designed in collaboration with Andy Timmons, the Keeley Muse Driver combines Robert Keeley's popular modded BD-style overdrive circuit with germanium diodes and expanded voicings. The result is one of the most sonically versatile dirt boxes you'll ever plug into. Indeed, guitarists have found this stompbox to be equally viable as a clean boost, a treble supercharger, a chimey tube-style overdrive, and a germanium fuzz. The Muse Driver features intuitive Tone, Drive, and Level knobs, along with a Tone voicing switch that cuts or boosts your low end and a Drive voicing switch that alternates between asymmetrical silicon and dual-germanium clipping modes. Beyond that, you can toggle between buffered and true-bypass switching instantly with a tap of your foot. Finally, this guitar effects pedal boasts 9–18-volt operation, netting you dynamic range and headroom by the truckload. The Keeley Muse Driver flaunts a magical combination of red-hot JFET transistors, germanium diodes, and op-amps; once you taste its harmonic-laden overdrive, you'll never take it off your pedalboard.

One pedal, many voices

At its core, the Muse Driver is a BD-style overdrive with intuitive Tone, Level, and Drive knobs. But, thanks to its AT/RK ("Andy Timmons/Robert Keeley") Tone and Drive voicing mode switches, the Muse Driver is capable of much more than your typical blue stompbox. The Tone switch leverages Robert Keeley's extensive modding experience, enabling you to cut low frequencies for added clarity or boost low-end for extra power. The Drive switch alternates between an articulate asymmetrical silicon clipping style and a dual-germanium-diode-fueled mode with a smoother, more compressed character.

Buffer or true bypass — the choice is yours

The Keeley Muse Driver employs an industry-leading buffer, ensuring both noise-free switching and long cable runs with zero tone loss. A good buffer will make almost any rig sound better. That said, there are many circumstances where true-bypass switching is preferable, especially if your guitar rig contains vintage fuzzes and other similar pedals. If that's the case, simply hold down the Muse Driver's footswitch for two seconds, and you can instantly toggle between true-bypass and buffered-bypass switching.
