“The rare John Hornby
Skewes (JHS) FZ-III fuzz pedal. Manufactured by Jen in
Italy in the 1970s, the JHS Fuzz features a very similar circuit, and
many similar components to later VOX Tone Benders, which at the time
were also being made by Jen. Features include (1) BC238B and (2) BC239C
silicon transistors, Attack and Level control, all packed into a blue,
rectangular, Tone Bender style housing.”
