Black Silk OC75 MkIII Style British Fuzz
2015 Edition – Hand Sanded, Robert Keeley signed, clear coated, then emblazoned with the BLACK SILK – BRITISH FUZZ LOGO! – 20 Limited edition units – Hard to Find Black Glass OC75 transistor circuit delivers thick fuzz effects
April 24th, 2015 — Edmond, OK — Keeley Electronics today announced it is building the Black Silk British Fuzz effect pedal. The pedal will be limited to 20 units. The 100% hand-built Black Silk is a modern compact circuit using the classic OC75 based design and was created for the most demanding fuzz effects lovers. The first two transistors in the 3 transistor design will be CV7003 PNP germaniums which are mil-spec OC44s, followed by a Mullard OC75. The Black Silk offers a wealth of tone bending vintage musical MkIII sounds with reduced noise, no gating, and a modern power supply.
With controls for FUZZ, TONE, and LEVEL the Black Silk makes it easy for players to dial in very wild amounts of fuzz. This design is not gated in any way like the Keeley Black Glass. It is very open sounding. There is no treble push in this design, so it sounds more “vintage-correct.” It is very interactive with the volume control on your guitar. For those wanting a MkIII sound, this is it! Furthermore, design modifications have solved temperature problems that can affect vintage fuzz units. A reverse polarity germanium diode at the final gain stage prevents temp problems. Players have the needed power supply inversion built in so that they can use a regular 9 Volt power supply.
Our design team focused on building a MkIII style circuit with a stash of Black Glass OC75 transistors that Keeley had in his collection. This type of PNP germanium pedal can be expensive, bulky, and can have variances in sound quality, so our goal was clear: create a best-in-class product that combines compact versatility, repeatable musical tone, and low noise in a compact effect. To achieve this, we employed several technical innovations from our Time Machine Boost and Holy Fuzz designs. We also use techniques to nearly eliminate temperature coefficient problems in germanium designs. The end result is that the Black Silk British Fuzz is vintage fuzz effect we are extremely proud of and excited to offer to our customers in this very rare and extremely limited edition and is ready for any stage, no matter how hot!
Like all of Keeley Electronics’ designs, the Black Silk is hand built in the USA using the finest components and construction techniques. It is housed in a beautifully powder-coated and rugged enclosure, includes true bypass switching, and features a 2 year limited lifetime warranty with world-class Keeley customer support.
