And yes, I don't need transcriptions of songs but that's only because I was classically trained (music in general and guitar) and have been playing for years. Takes practice but a good way to start learning most songs is to pick the bass line first. Most bass players follow the chords so you can easily figure them out when you see what the bass is doing. Doesn't work when transcribing avante garde jazz, of course.
As for wrist position for left hand, if you remember four things, proper technique tends to take care of itself and you minimise the risk of long-term injury (and play better!);
1) Play right on the very tips of your fingers. Really exaggerate the arching of your fingers to make this possible.
2) When you get that right, you leave a gap of about 2-4cm between the webbing of your hand and the bottom of the neck. Make sure there is that gap at all times. Poor technique and playing happens when your hand is touching the bottom edge of neck.
3) Keep the tip of your thumb roughly lined up with the tip of your middle finger when playing chords, especially when sliding up the neck.
4) Imagine that someone has drawn a line from the base of the neck to the headstock which splits the neck into two halves. Keep the top pad of your thumb on that imaginary line when you play.
This link is reasonable;
If you do the above you'll sound better, your hand will be more relaxed, you'll be able to play for hours pain-free and you won't get injuries in the years to come. That said, it's really hard to do this online so I suggest you get yourself a teacher, even just to start you off.
AgentTBY, I want your Tele.
The Gibson self-tuning guitars, I'm a bit curious because if you're doing lots of tuning changes on stage, they'd probably save a bit of time. I've heard they sound quite nice too. I'll probably have a better look at them once they've been out in the wild for a while because new tech stuff like that tends to be fine in a studio setting but fall over under heavy gigging pressure. My MIDI guitar has held up surprisingly well considering it's a good 18 years old; I guess they went all out to make sure the MIDI worked and stayed working when they made them because it really is a beautiful guitar to play.
EDIT: Anyone else given a Chapman Stick a go? I tried one the other day, very cool instrument. Only problem is that the only people who've taken it up on a regular basis are jazz wankers or world music hippies so the back catalogue on it is pretty esoteric and far too nice. I just wish a metal player would take it up and bash it around a bit.
