The Williams - Vintage Tone MK11 Professional is a very faithful recreation of the very early Tonebender MK11 Professional fuzz pedal built by Sola Sound in the UK.
This version is closely associated with Jimmy Page tones, it has a very slightly more mid tone than the standard MK11, a touch mellower and nice and loud.
Although there is much speculation as to what Page actually used and when (check Goggle for all the conflicting opinions), this model certainly does sound the closest of the lot. Of course there isn't just the classic Led Zep Page tones in here, there is a wealth of many more definitive vintage tones of guitarists such as Jeff Beck and many others.
Ben King, guitarist with The Yardbirds, the band that launched Page, Clapton and Beck, tours worldwide and records with a Williams MK11 Vintage Tone loaded with 3 Mullard OC81D transistors. You cant get a much better recommendation than that. (check out the video further down the page of Ben playing his OC81D MK11 with The Yardbirds).

One of very few MK11 Tonebender's now available offering Genuine 1960's OC81D Mullard transistors as used in the original. ALL Mullards I use are only ever Genuine Mullard produced transistors that I know the source of. Be assured I will NEVER EVER use modern copies or any other junk! My Mullard OC81D stock usually comprises of metal can, white rubber jacket and green rubber jacket types. They are all exactly the same soundwise, produced by Mullard in the UK for different markets or at different years.

The MK11 cleans-up beautifully by rolling back the guitar volume pot, essential for achieving some of those vintage rhythm tones we know and love. Crank it back up and all the sustain, warmth and magic of a classic vintage MK11 Tonebender is right at your fingertips.
