At the end of band practice yesterday, we decided to have a little fun and switch instruments. Our drummer switched with the rhythm guitarist, and I switched with the lead guitarist. We played a few of our easier originals, and then tore into a few random unrehearsed covers, among them several songs from Green Day's "Dookie" album; we played "Basket Case" and "She" reasonably well and butchered "Having A Blast". If you're familiar with Billie Joe Armstrong's guitar style, you know he generally uses quite a bit of palm-muting, which I recreated pretty faithfully. By the end of the instrument reversal, my right index finger was starting to hurt pretty badly, but that happens reasonably often when I play guitar standing up so I didn't think much of it. When we put the instruments down, I noticed I'd rubbed off a large chunk of skin above my index fingernail, and the spot was bleeding pretty badly. It didn't take long to discover that I'd also bled all over my guitarist's pickguard and pickups It washed off easily...I kinda wish I'd been playing my Squier at the time; I'd have just left the blood there...that would be so punk rawk My guitarist also managed to hurt himself; my bass gave him a big blister on his thumb. So, the lesson is that apparently my guitar technique, particularly palm-muting, needs some work. Anybody have any interesting injury-by-instrument stories? I know somebody has to have stabbed themselves with a drumstick or something, right?
