I own a MIM Fender Jazz Bass and really want that beatiful Jazz+Flats sound. JPJ is a hero of mine and I bought a set of Fender 9050 ML's (50-65-85-100), which i thought would be best compared to what i have it strung in right now with rounds (45-65-80-100). Granted I knew there'd be a tension increase, but not like....this. I tried putting on the E string earlier, all was going well until I realized I was heading into much more tension than desired. the string started to set much higher above my fretboard than the others. My bridge is quite low and the action on my other strings is as well. I've adjusted my truss rod quite a bit just to compensate for the tension from the rounds. as i turned the tuning peg a slight bit more, *JUST* to obtain the correct pitch of the low E, I heard a little noise that sounded like wood cracking. I immediately stopped, and started to unwind the string and put the old one back on. tonight i decided to give it another try, instead I've started with the G string. the same thing there, i feel like the string is going to snap if i even try to get it to correct pitch. a comfortable action on this string is around the pitch of E three semitones below it. so i dont know what to do. i don't want to damage my instrument and these strings seem to be brutal. otherwise, just messing around with a detuned flatwound string on the board feels great and i'd love to use them if i wasn't so afraid the neck was going to snap in half. after adjusting the E or the G close to correct pitch, plucking my A string aggressively resulted in a metal 'twwaang' i could only assume was the truss rod. but if i keep my current strings, it goes away. Any help with what actions to take would be appreciated!
