i was just poking around on my new cirrus 4 that i bought on eBay and discoverd that the nut on my truss rod is totally stripped. i've read some threads on the subject and am hopeful that the nut can be replaced and the rod itself is fine. i'll take into my guitar tech asap. my question? how could this happen? this bass is flawless, practically brand new in every other way and the neck plays well (i was gonna give the nut an 1/8 turn to decrease the relief a tiny bit but i can get by without it). i know i'm gonna have nightmares tonight of my beautiful new bass sitting in the backseat of a parked car in 110 degree heat with the neck warped like a longbow. seriously though, if anyone has seen anything like this before on a relatively new instrument i'd really appreciate your perspective.
