if i sound like a moron for posting this, i'm sorry but i just learned this the other day. i can't remember if it was mentioned on this board or the tele modders. but you can adjust your bridge while it is on the guitar with a very small allen wrench. i don't what exact size, but it is the one i use to adjust saddle heights. it was in the back of my head bugging me, and i thought i'd try it, i guess it was more of a subliminal suggestion. imagine my suprise when i figured that out. i've owned a jazzmaster for 8 years now and was always taking the strings off to adjust the bridge height. hope this helps someone else and relieve some headaches. i know it did for me.
