Pothos, big name guitars are expensive, but they always were. In The Beatles' Gear Andy Babuik gives the price of the various guitars, plus the modern equivalent. They were not cheap back in the Sixties, which is why so many were bought on credit.
I have been trying to work out the sound of classic guitars to classic tracks.
Fender Telecaster - Led Zeppelin * Whole Lotta Love. Gretch - Stray Cat's * Stray Cat Strut. Common Everybody - Eddie Cochrane. Rickenbacker - The Beatles * I Feel Fine Gibson Les Paul - Sister Rossetta Tharpe Frank Zappa. Les Paul. Fender Stratacaster - Pink Floyd * Dark Side of the Moon. Hank Marvin.
Pothos, I'm sure that when those records were made, you could somewhat identify different guitars. However, with modern studio technique and equipment it's possible for a guitar to sound like almost any model, and also to emulate any amp. Musicians go on tour with numerous guitars, for example Steve Stevens with a shedload of Les Pauls, because each has a different sound [due to custom pickups etc] Whether the audience can tell the difference is another matter.
Here's a six-string version of the famous Hofner Violin Bass, which is fairly rare....
Then there was the Futurama, such as the one George played before he got his Gretsch Duo-Jet.
George's Futurama was a somewhat Strat-like (three single-coil pickups on a solid-body) guitar with individual on-off switches for each pickup. That means that you can get any pickup combination possible, which a Strat can not do unless it has been modified with an extra switch, push-button usually. The problem with three on-off switches is that two (on-off) to the third power (three pickups) equals 8, not the seven pickup combinations, which means one of the possibilities is total silence.
When someone not familiar with the guitar gets to experimenting with it, and all three pickups are off, they begin to turn up all the volume knobs all the way up, then change a switch, and then amp's speaker blows. And perhaps eardrums are damaged.
One of the strangest guitars ever made was once owned by John Lennon. Who happened to see one in a guitar shop in lower Manhatten one day. Only 15/20 of these guitars were ever made. It is the Sardonyx 800 D II.
John used it during the recording of the Double Fantasy lp.
You'll notice this picture sleeve they are wearing the same clothes as in the pics of John with that guitar. So it was probably taken as they were going to the Record Plant that day, in front of the spot where John would later be assassinated.
