Independent shopping perspective
The Korena take
Built with Andy Timmons, the Mk3 Driver is an overdrive pedal with two drive choices and two EQ curves to shape its response. Select the brighter, articulate LED clipping or the smoother germanium-diode option, then use AT or RK tone settings to refine the low and high end. Its bypass mode is selectable between buffered and true bypass, while 9–18 V operation offers expanded dynamic range and headroom.
Strong match
Who this is for
- Building an overdrive sound around either brighter articulation or smoother germanium-diode saturation.
- Pushing tube amps or single-coil pickups with the RK tone setting.
- Choosing buffered or true bypass to suit the signal path in an effects rig.
