VOX SOUND LIMITED - Colorsound / Sola Sound Wah
A wah pedal made for Vox by Coloursound / Sola Sound in 1970 - the "Vox" in question probably being "Vox Sound Limited".
The blue Erie capacitor has the date code "YYS" = 5th week of 1970. The inductor is marked "70" too.
It is just possible that the pedal was produced (and delivered) in the last days of "Vox Sound Equipment Limited". But "Vox Sound Limited" (from mid 1970) seems on balance more likely.
