What’s the difference between this and any other POS European instrument from the 1960s? Just the Wyman thing? Or was Framus high-end in 1964?
Not high-end, but they were some of the first new electric instruments that British musicians could afford and they had a lot of players, especially on bass. They were the largest guitar manufacturer in Europe during the 60's, so stateside they were sorta of oddities.
This is absolutely correct.
Back in the early '60's, Fenders and Gibsons were really tough to get a hold of across the pond. (Not that the British rockers didn't WANT those instruments, they just weren't readily available and were extremely expensive when they WERE available.)
With the British Invasion, the market in Europe really opened up, and THAT'S when most of the "Rock and Rollers" started having more options on bass, and most of those early acts switched brands....
These were never very good instruments, it was all they had access to.
They were definitely good enough to be used professionally and quite a few artists from that decade still remember them fondly.
