Keeley Black Glass British Fuzz - Limited Edition

The Keeley Black Glass British Fuzz - Limited Edition is a 100% hand-built modern compact circuit of the classic OC81 based design. It was created for the most demanding fuzz effects lovers. The Black Glass offers a wealth of tone bending vintage musical MkIII sounds with reduced noise and treble response and a modern power supply.

With controls for FUZZ, TONE, and LEVEL the Black Glass makes it easy for players to dial in very wild amounts of fuzz. Modifications to the circuit allow for an increased high frequency not heard of before as well as ultra-low noise.  Furthermore, design modifications have solved temperature problems that can affect vintage fuzz units.  Players have the needed power supply inversion so that they can use a regular 9 Volt power supply.

There are only 150 of these available world-wide, so be sure to get yours before they're gone!

A Word From the Maker:

“Our design team focused on building a MkIII style circuit with a stash of OC81D transistors that Robert Keeley had in his rare stock of electronic parts. 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 Glass 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!”
