Hey Clinton, do you remember Bourne and MacLeod? When things got really noisy, MacLeod (the tiny Scottish piper and tough guy) would pull out a .45 (with blanks thank god) and shoot it off a couple of times. Geez, did it get quiet fast!
No need to tune after you put your capo on, if you simply place it right next to the fret. It won't stretch the strings that way. The best capos for keeping in perfect tune are Shubbs and Dunlop C clamps. Keysers are the simplest to use, but because you can't adjust the tension, are a bit iffy for keepiing the guitar in tune. Another trick that is INCREDIBLY useful (if you care about perfect tuning) is to cut two tiny "V" shapes in the rubber, under the two bass strings. This REALLY WORKS! I've been doing on capos for 12 strings for twenty five years, but it works great on Kaysers (if I keep spelling it differently eventually I'll get it right), and with the grooves, the capo doesn't have to be as close to the fret.
