I wouldn't (and couldn't) pay $20,000 for a guitar or bass no matter the history.
Jerry's Alligator, Wolf or Tiger?
Jack Cassady's #1?
Phil's Osage Orange, Mission Control or The Godfather?
Jimi's Strat?
Clapton's Blackie, Brownie, or The Fool SG?
Les Paul's original Log?
BB King's Lucille?
Willie Nelson's Trigger?
Paul McCartney's original Hofner bass?
Keith Richard's Tele?
Pete Townsend's SG?
All instrument I would pay $20K for, if I could afford it and they were available. Hey, do I detect the seeds of another thread here?
