I suppose on the plus side the resale value of a 'relic' guitar is vastly higher than an identical guitar that got in that state from heavy use (unless its a really old genuine vintage, obviously).
You say that, but have you ever heard the one about the mint relic?
I once heard a story about someone allegedly selling a relic strat, and one buyer was asking him if there was any wear on it. i.e. something that was not there when the guitar was brand new. upon finding out it was possible there was SOME extra wear on it, the guy was no longer interested in it, if it was no longer "mint condition"
I still can't get my head around that.
As far as my own guitar prejudices go, I did end up not wanting to play a Les Paul for years.
I've had a black Epiphone Les Paul since 2001. I bought it with money I got for passing my A-levels. I really liked it at the time. Then, The Darkness hit big. put me right off them, to the degree that in 2004, when I had the opportunity to buy another new guitar with money I had left over from my Year abroad in France (part of my Uni course), I bought an Epiphone Dot, purely because Justin Hawkins had put me off Les Pauls so much I couldn't bear playing one. Especially considering for a while I wanted a white Les Paul, being a huge Manic Street Preachers fan.
I'm long over it now of course. I came to realise that no matter what guitar I choose to play, I will find someone dodgy that plays one like it.
That said, I'm still opposed to "metal" guitars, pointy headstocks and such.
