Vintage Tone Professional MK11 - Classic MK11

The Williams Vintage Tone MK11 Professional is a very faithful recreation of the legendary Tonebender MK11 Professional fuzz pedal. Originally built by Sola Sound in the 1960's, the MK11 Tonebender instantly became a mainstay for many legendary guitarists such as Jimmy Page and Jeff Beck. Probably the greatest Fuzz pedal ever.

Williams MK11 Professional OC81D Tonebender

At full Fuzz, the fuzz is big and dirty but still warm, organic and articulate. Notes sustain on and on, eventually ringing out into dying upper harmonics on certain frets. Bring back the volume on the guitar and the MK11 takes on a different feel, things start to clean-up, starting from a dynamic crunch superb for Jimmy Page style rhythms through to a shimmering, almost clean tone with a slight crunch.
