1960's Marshall Supa Wah

Vintage Marshall Supa Wah from the late 1960's. Fully functional and all original except for the screws which hold the bottom cover on. This pedal has not left my house since purchase and was only used for a few recordings. True collector's item. Made from 1967-1974. The based on advertisement for other identical pedals, the serial number and internal configuration puts it anywhere from 1968-1970.
