I'm still acquiring gear with the hope of finding "my" sound. Also, still learning to play, so I guess that goes hand in hand. Being new, I'm trying to focus on playing instead of tweaking, but I must admit that the urge to "buy a sound" is seriously irresistible at times.
All that said, going back to the earlier points on the Les Paul vs the Strat (I've been away for a while and just catching up) I've got to say that while I do love the LP sound, I don't particularly like the look of them, and I HATE the feel. Every time I try to play a Lester, I feel like it sets me back and makes me a worse player. I just can't get them to work. The weight, the uncomfortable feel of the body shape and that (for my hand) awful neck shape just don't work for me. But that's me, and only me. For other people, the LP is the ideal guitar. Ace Frehley, Slash, Page...these guys know a thing or two, and LPs obviously work for them, so who am I to argue?
Its no different than framers on a construction site. Some guys swear by an 8" Skil saw, others want a 12" sliding compound mitre. The odd old guy may even use an old-school hand held ripsaw. Guys use what works for them, and who cares, as long as the job gets done.
That's why there are so many different guitars...what works for one person will not work for someone else. Play your music, make your sound.
