Overview<\/h3>\n\n\n\n

Introduced in 1968, the Tone Bender MKIII was the latest incarnation of the series of Tone Benders that Sola Sound had been supplying to Vox (among other brands) since 1966. By the time that Sola Sound were producing the MKIII, their fuzz boxes were no longer being built into cast aluminium enclosures, and instead, the MKIII appeared in a pressed steel casing. These newer enclosures were painted in a dark grey hammertone finish, and were printed with a far livelier and attractive set of silk-screened graphics.<\/p>\n\n\n\n

Sola Sound continued to supply Vox with the Tone Bender MKIII until well into the 1970s, with the fuzz circuit undergoing various further changes over the years. Pedals that are formally labelled as \u2018Vox Tone Bender MKIII\u2019 could have been built with any one of at least three entirely different fuzz circuits, and the only way to recognise the specific type<\/em> of MKIII is by inspecting a pedal\u2019s cosmetic features and\/or the electronics inside.

Some of the earliest Vox Tone Bender MKIII fuzz boxes were built with a silicon transistor circuit, and featured only two control knobs. These Tone Benders, \u2018with treble \u2018n\u2019 bass boost\u2019, were in production by August of 1968, when a Tone Bender MKIII with only two controls was demonstrated at the British Musical Instrument Industries trade fair at the Russell Hotel in London.<\/span>1<\/sup><\/a><\/span> (Photo credit: J. Bagwell)<\/p>\n\n\n\n

The electronic circuit in these pedals is unlike any other fuzz box design known thus far. The two controls allow for the user to vary the volume and the tone of the fuzz sound, and what makes this model particularly unusual is that the tone control continues to function even when the pedal is disengaged in the signal path.<\/p>\n\n\n\n

Tone Bender MKIII pedals \u201cplus Bass and Treble Boost\u201d were still being advertised in the press by early 1969,<\/span>2<\/sup><\/a><\/span> but it is unknown how long exactly the model remained in production. The small number of surviving pedals suggests that the two-knob Tone Bender MKIII was only a relatively limited offering.

By the end of the 1960s, Sola Sound started building Tone Bender MKIII fuzz boxes with what would become one of their most successful circuit designs. This version of the Tone Bender MKIII featured a germanium transistor circuit that was loosely based on the earlier Baldwin-Burns Buzzaround<\/a>. It came with adjustable controls for the volume, amount of fuzz, and tone of the effect. (Photo credit: S. Castledine)<\/p>\n\n\n\n

The same germanium transistor circuit that Sola Sound built into these three-knob Vox Tone Benders, between the late 1960s through to approximately the mid-1970s, was also supplied to companies like Rotosound<\/a> & Park<\/a> for their own versions of the Tone Bender MKIII. Sola Sound also sold the Tone Bender MKIII under their own company\u2019s brand name for a limited period of time, before developing their Tone Bender MKIV<\/a>.

For a short period of time in the early 1970s, the Vox Tone Bender MKIII was built into a cast aluminium version of the familiar \u2018MKIII\u2019 enclosure, instead of in Sola Sound\u2019s pressed steel casings. These cast enclosure pedals featured the same germanium transistor fuzz circuit as Sola Sound\u2019s pressed steel pedals, but they were fitted with stickers noting the address for the new factory set up for \u2018Vox Sound Limited\u2019 (VSL) in Hastings, Sussex. It\u2019s likely that these pedals were manufactured \u2018in-house\u2019 by VSL, based on Sola Sound’s design, rather than by Sola Sound themselves. (Photo credit: A. Souleyman)<\/p>\n\n\n\n

The youngest of the Vox Tone Bender MKIII pedals featured a silicon transistor circuit, based around the Electro-Harmonix Big Muff Pi design. These pedals were supplied to Vox by Sola Sound approximately during the mid-to-late 1970s, and were identical to Sola Sound’s own Colorsound Jumbo Tone Bender pedals.

Much of our understanding of the development of 1960s fuzz boxes comes from analysis of surviving pedals themselves, and so photos of pedals belonging to readers are particularly useful in furthering this research.<\/p>\n\n\n\n

If you would like to contribute pictures of 1960s-era guitar effects to Fuzzboxes.org, then feel free to send in any pictures via the uploader below. Photos are greatly appreciated, and any submissions are not published on this website without advance agreement with the contributor.<\/p>\n\n\n\n
