The British Pedal Company Professional MKII Tone Bender OC81D from the Vintage Series is an authentic reproduction of the 1966 Professional MKII Tone Bender pedals designed by Gary Hurst. In contrast to the MKI.5, the MKII features a 3-transistor circuit that utilized either 3x OC75 or 3x OC81D transistors, resulting in enhanced sustain. The MKII equipped with OC81D transistors can be heard on numerous Led Zeppelin tracks by Jimmy Page, including 'Whole Lotta Love.' This is also the pedal that Jimmy Page was seen using in the 2008 documentary 'It Might Get Loud.'
