BK Butler 911 Tube Driver
Unknown brand · pedal
The BK Butler 911 Tube Driver is a boutique overdrive built around a real 12AX7 vacuum tube, producing rich, buttery, singing overdrive tones with a saturated, harmonically complex character that has never been fully replicated by solid-state circuits. It ranges from a smooth, light drive or clean boost to a thick, heavy overdrive, and is closely associated with Eric Johnson's singing violin-tone lead sound, David Gilmour's go-to drive since the Division Bell album, and players including Billy Gibbons, Joe Satriani, and Joe Bonamassa. Its tube-driven response reacts strongly to pick dynamics and interacts closely with the specific amp it's paired with, which also means it can be finicky and less consistently versatile across different amps. It suits players chasing a distinctive, warm, tube-driven overdrive character worth dialing in with the right rig.
