Hello, I am at present researching and collecting information regarding the Guitars and Amplifiers that the "Sex Pistols" used between 1975 and 1978. Glen Matlock played a Fender Precision Bass in 1975/76. I'm seeking advice and information (Colour, year, pickups, etc) of this particular guitar. "Am I correct that it is natural ash body, 1-piece maple neck/fretboard and a 4-ply tortoise shell (Brown) pickguard". Video: First 30 secs Any help in identifying this Bass would be most appreciated. All the best.
