The Epiphone Rivoli was much more popular in the UK. I owned an EB2. Then I bought a used Fender P in January 68. After one rehearsal with the Precision the Gibson felt like a plank. I never played it again.
Yeah the Gibsons/Epiphones had a unique sound.
I can one up you though, 1965 I bought a used Mosrite Ventures model bass. Thought it was so cool. Then a friend came over with 65 precision. Played them both through my blackface 64 Fender Bassman. Enough said.
