Mayer was originally an acoustic engineer working for the British Admiralty on underwater research projects.
At a time when guitar effects were virtually unknown, he designed and built fuzz boxes for leading English guitarists such as Big Jim Sullivan, Jimmy Page, and Jeff Beck.
After introducing himself backstage and talking in-depth about tone and a desire to create a totally different sound, he was invited by the guitarist to a gig the following week.
Via a small amp back stage, Hendrix listened to the Octavia and was really impressed and excited by what he heard.
