Peter Green bought a Fender Stratocaster during his first visit to the US, as did Jeremy Spencer. This is was filmed 8/68, after FM's first visit to the states two months prior.
Peter Green is playing a three selector switch Strat with no knob and one that's not from Fender. That's as second hand as they come!
