Hey Zoggy, congrats on your purchase. Personally, I play sitting down. If you're planning on playing gigs sometime soon, definitely practice standing up. Theres a world of difference between the 2. I have found, for example, its difficult for me to use the low E string far down the fretboard while standing, but I can do it sitting down. (I get lazy and don't learn how to effectively use the fretboard. I just go up and down the scale on different strings.) So to say the least, I screw up much more standing. I'd also recommend keeping your guitar strapped tightly, as opposed to having it loose and hanging low. You won't look as cool, but you'l play better.

Have fun man. :cool:
