VOX SOUND LIMITED - Colorsound / Sola Sound Tonebender Mark III
A tonebender pedal made for Vox by Coloursound / Sola Sound in 1971 - the address on the underside being Hastings, Sussex, England.
"Vox Sound Limited" moved to St-Leonards-on-Sea/Hastings in two stages: the factory first in the late summer of 1971, then the office, summer of 1972. For an overview, see this page. At some point early in 1973 Vox Sound Limited (VSL) effectively came to an end as a public-facing business.
Livery and labels are the same as the "Hastings Wah" - see this page.
