So this came up in the withholding design improvements thread: And it made me think; not only would it be interesting to have a thread discussing this specific topic, but also a series of threads imagining what the world would have been if certain musicians, instruments or technologies were different or had never existed at all. What would the world be like today without Scott Joplin? Miles Davis? The Beatles? The Roland 808? MP3s? So for this particular thread there's a couple scenarios to consider: Scenario 1: Leo Fender never invents the P or J basses. Scenario 2: The P or J basses are invented, but Fender goes out of business and ceases to exist in the early 80s. Discuss away!
