The Tone Bender MK1 by Sola Sound is a historically significant two-transistor fuzz box that was built in the mid-1960s. It was a transitional model between the earlier Tone Bender MKI and the later Professional MKII. The original Tone Bender MK1.5 featured a cast aluminum enclosure, a simpler circuitry compared to the MKI, and was produced in larger quantities.
The circuitry of the Tone Bender MK1.5 typically included a 'textbook' negative-feedback amplifier circuit with two Mullard OC75 germanium transistors. Some early models were fitted with Impex S3-1T transistors. The pedal was also equipped with a 500kΩ level potentiometer, extending the lower frequency cut-off and allowing for a bassier fuzz sound.
Unusual variants of the Tone Bender MK1.5 include the "Goldie MK1.5" housed in gold-painted enclosures, and versions with Impex transistors. Additionally, Sola Sound acted as an OEM, supplying the same electronics to other brands such as Dallas and Rotosound.
Notable users of the Tone Bender MK1.5 include Mick Ronson, who used the pedal before achieving global fame with David Bowie. The Beatles were also photographed in the studio with a Tone Bender in April 1966.
The Tone Bender MK1.5 is a significant piece of music history and has been used in specific recordings such as Him & The Others' "I mean it", the Transatlantics' "Don't fight it", and Downliners Sect's "Glendora".
