The British Pedal Company Professional MKII Tone Bender OC75 from the Vintage Series is a detailed replica of the 1966 Professional MKII Tone Bender pedals created by Gary Hurst. Unlike the MKI.5, the MKII had a 3 transistor circuit which, based on production and supply, comprised of either 3x OC75 or 3x OC81D transistors and offered increased sustain. The OC75 loaded MKII can be heard on the iconic track 'Keep on Running' by The Spencer Davis Group.
