Ultra rare 1980-81 BK Butler Mini Boogee preamp/overdrive/distortion pedal, the predecessor to the famous 'Tube Driver' pedal. One of the few made in 1980-81 before Randall Smith from Mesa Boogie requested they rename the pedal for copyright reasons. Uses two original USA General Electric 12AX7 tubes for four consecutive triode gain stages, and features 3-band tone control, and Drive and Master controls. Made in the USA.
Almost never used over the last 30 years, and is in original condition. Rare factory 240V model. Missing feet.
