Charing Cross OC75 – MkIII British Fuzz

2015 Edition – Emblazoned with the Charing Cross and Black-on-Black British Subway Design!

10 Limited edition units – Full Compliment of 3 Black Glass OC75 transistors.   Keeley’s MkIII circuit delivers perfect fuzz.

December 29th, 2015 — Edmond, OK — Keeley Electronics today announced it is building the Charing Cross British Fuzz effect pedal. The pedal will be limited to 10 units.  The 100% hand-built Charing Cross is a modern compact circuit using the classic MkIII design and was created for the most demanding fuzz lover.


The Charing Cross offers a true tone bending MkIII sound with genuine OC75 transistors, reduced noise, minimal gating, and it can be powered with a modern power supply.

With controls for FUZZ, TONE, and LEVEL the Charing Cross OC75 Fuzz makes it easy for players to dial in very wild amounts of fuzz. This design is very slightly gated like a true MkIII would sound. There is no treble push in this design, so it sounds more “vintage-correct.”  It is very full and smooth sounding. In fact, it is slightly smoother than an MkI or MkII design. 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 temperature problems.

Our design team focused on building a true MkIII circuit with a stash of Black Glass OC75 transistors that I had in my 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 used techniques to nearly eliminate temperature coefficient problems inherent in germanium designs.  The end result is that the Charing Cross OC75 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!

Like all of Keeley Electronics’ designs, the Charing Cross OC75 Fuzz is handcbuilt 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.

The Keeley Electronics Charing Cross OC75 Fuzz goes on sale December 29th for $399. Visit for more information about the full lineup of award-winning Keeley Electronics effects.

Units are being built and will ship starting the first week of January 2016.
