Andy Timmons Full Range Overdrive

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.

Classic blues driver circuit with decades of Keeley mod experience Germanium based overdrive crafted with Andy Timmons direction, AT/RK Tone Switch cuts lows for a clarity or boosts low end for power AT/RK Drive Switch alternates between asymmetrical silicon to dual germanium diodes. It offers the ability to do Buffered Bypass or True Bypass which is able to be changed instantly depending on your rig’s needs. Sporting JFET Transistors, Germanium Diodes and Op Amp Gain combine to form harmonically rich overdrive.

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 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 and 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.
