British Pedal Company MK I Tone Bender

They say:

The BPC MKI Tone Bender is a detailed replica of the original 1965 Metal Case Tone Bender pedal created by Gary Hurst in London, England. The BPC MKI features the same transistor specification as the original so includes 1x OC75 + 2x 2G381 this configuaration has a unique tone which cannot be replicated by the often offered 3xOC75 version. It was this version which found its way into the hands of artists such as Jeff Beck, Pete Townsend and Mick Ronson and can be heard on many classic tracks such as ‘Hang onto yourself’ and ‘Moonage Daydream’.
