Keeley Andy Timmons Muse Driver Full Range Overdrive Pedal

A full range overdrive with tons of versatility, Keeley's Andy Timmons Muse Driver offers everything from chime-y drive tones to square-wave, germanium fuzz!

The Muse 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 Muse 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 Muse 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 Muse 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 Muse Driver circuit combines JFET saturation, diode read more 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.

Muse Driver - Buffered Bypass or True Bypass
The Muse Driver features Keeley's industry leading buffer for noise-free switching. Keeley Electronics has 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 the foot switch for two seconds and the pedal will switch between true-bypass and buffered bypass! You decide what works best in your rig.

Made In The USA
They design, engineer, and manufacture the Keeley Electronics/Andy Timmons Muse Driver in Oklahoma City. Everything about the Muse Driver is geared towards the professional musician and their quest for an inspiring tone when performance demands it. From the meticulously built circuit boards to the fabricated aluminum enclosure; Keeley Electronics makes guitar effect pedals like finely crafted musical instruments.

A Note From Andy Timmons:
The Muse 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.

I'm not incredibly familiar with the work of Andy Timmons, but from everything I've seen and heard the man knows tone, and Robert Keeley knows how to build pedals. This is a great pedal. Very responsive to your guitars volume control. So much so that I think I can eliminate my super low gain pedal that sits in front of this and just work my volume knob to achieve that edge of breakup thing. It's got a great range of overdrive and sounds good at all gain levels. It's not going to get you into metal territory on its own but that's not what it was designed for. It's a Blues Driver on steroids. Check out the videos on Keeley's YouTube channel. It does not disappoint.
