MOSFET Driver

Compared to the BK Butler Tube Driver, this MOSFET-driven circuit chases the warm, harmonically complex overdrive that became David Gilmour's secret weapon on some of his most iconic tones. The real Tube Driver uses an actual tube in the signal path; this design approximates that organic, slightly saggy breakup with MOSFETs — making it far more practical to build and gig than hunting down vintage NOS units.
