iPhone pic again, but of all the guitars that I own, these three are my favorites.
L: Carvin CS4
M: Ancient Ibanez EZ
The Carvin is the best playing, best sounding guitar that I've ever owned. I've only played a few that keep up with it. It's absolutely fantastic, and it's what I reach for about 90% of the time. From a player's perspective, this is my favorite.
The EX, however, is "that guitar" for me. I bought it with my paper route money when I was 13, traded it in at Daddy's Junky Music when I was about 15, and then found it again (the very same guitar) when I was 17 and have never let it go since. It's absolutely amazing, it sounds like nothing else. It's the combo of huge sentimental value + really unique sounding guitar. If my house caught on fire, the EX is the only one I'd run back in for. In all my years playing, I've probably logged more time on this one than all of my other guitars combined. It's worth absolutely nothing to anyone but me, but honestly if someone offered me ten grand for it, I'd turn them down. it has a BFGoodrich sticker on it that I put on there when I was 15, that reminds me of old friends and good times. It's a piece of my life, so to speak.
The RG550 is both one of the nicest Ibanez's I've ever played, and one of the nicest things that a relative stranger has ever done for me. I "knew" Mike online and we hung out once or twice before he refinished it for me, but the amount of work that he put into it combined with how fantastic it sounds - I'll never let it go.
