I upvoted your post, but at the same time, I did purchase a John Lennon signature Epiphone EJ160E (fashioned after the Gibson J160 that Lennon
did play at some point). It had a stenciled Lennon signature subtly positioned on the top. Why did I buy it? Well, I thought it was "cool." And since it was an Epiphone I got a good deal on it for just 300 bucks. It really didn't sound that good, and the pickup didn't seem to work that well, and I ended up selling it (for $500
) Other than that, like I said, the fact that some famous guitarist played a particular model hasn't really been my motivating factor in what guitars I go after.
