On the other hand, I could see that for some successful performers, the purchase could be a sound financial investment if fans are just a bit more excited about hearing their favorite musician playing a rare instrument live than they would otherwise be. One might be able to recover the purchase price of the instrument through increased ticket sales.
I once turned up to a pub session and saw this hairy-looking person with a complete PoS no-name guitar. It had holes in the body and looked like it was held together with tape.
Even so. Surprisingly good sound. Sweet playing.
Complete opposite to the guitar nerds who turn up with gleaming prestige instruments they fumble around on.
I found out afterwards he'd been in a household name UK pop band in the late 60s.
[edit] I think it might have been a Fender Jaguar actually, it looked terrible!
Many guitarists fetishize the 59 Les Paul because of the sound. The trick is that '59 Les Paul might not sound any different objectively, but the musician knows they are playing an iconic and rare instrument. This can make the musician play better than usual. Guitarists often attribute this to the "mojo" in the guitar; the trick is the mojo is in the player's belief.
