Oh of course, if anything the tele shape and wood is slightly detrimental to the sound, but it has the advantage of being far more comfortable to play than a Les Paul or my Washburn and doesn't weigh a ton!!!
I agree that the amp and pick up combo has more influence on the sound. But I think the feel and style of the Guitar has more influence on your playing... well, my playing anyway.
Absolutely. You gotta like the guitar you're playing or you won't want to make any sounds at all.
I love Les Pauls but it is a bit of a mystery to me that they've remained popular for so long. They are a bitch to play sometimes. That heel area is a motherfucker. I love playing mine, but I don't do much upper fret noodling, so it's okay.
