I have two signature guitars (which is a sizable % of what I own).
 
	1. Mike Campbell Duesenberg.  I kind of wish it didn't have such a flashy paint job, because my technical prowess doesn't live up to the racing stripe.  But it's just sooooo fucking gloriously well engineered.  Easily the most well-intonated, stays-in-tune, plays-like-butter guitar that I've ever owned, gets a pretty wide range of sounds (bridge humbucker + neck P90), and it sounds fantastic through almost any amplifier.  It turned me into an evangelist for Duesenbergs.  I'll never sell it.  
 
	2.  Malcolm Young Gretsch - I bought it used, after the original owner had it custom painted candy tangerine, swapped out the pickups, put a Bigsby on it, and then put it right back in its case forever.   I know, I know... why would you buy a signature model and then heavily modify it?  I don't know.  After I bought it, I took the Bigsby off and made it back into a hardtail.  It's probably the guitar I play the least, but it's just super appealing to me.  I think it's cool as shit.  I'll try to put a photo up this week.  
 
	 
 
	(edit) Used to have a George Harrison signature Gretsch that I impulsively bought during a trip to New York, but just never bonded with it and sold it.
