Kneck rattling E string and Buzzing G Sring

Chili · #1 01-01-2008, 08:24 AM

i've recently been adjusting the truss rod of my MM Stingray, and hightened the bridge, i've slackened the truss rod quite abit, but only half turns at the most, and then leave for an hour or more, but how do you know whats to loose or to tight? i know your meant to hold down the first fret of the A string, and hold down the string at the bottom of then neck with your elbow and pluck the string, it should at leats wobble a little bit, if it doesnt, then its to tight, but how do you test if its to loose?
anyway, when i pluck the E string hard, the kneck rattles, sounds like its coming from the top of the neck, around the first 5 frets, and when i pluck the G string, it Buzzes loads, and both is only when i play them open, the notes fretted are fine, could this be becouse i've loosened the truss rod to much?

Measure the relief. Refer to the stickies at the top of the page. Relief is typically measured at the seventh fret with a straight edge and feeler gauges. If those tools are not available, capo or fret at the first fret and at the neck body join and use business cards. Also measure string heights at the twelfth fret. Post data and get answers.

Buzzes on open strings are usually related to low slots in the nut. But it could be a phenomenally bad setup. Until the data is in, it is impossible to diagnose.

BTW, half turns and waiting are unnecessary. Turn the truss rod nut until the adjustment is correct. Then do the set up. The only time that harm can be done is when tightening a bottomed out nut. If it is fighting or squeaking, then it is time to stop and use other measures.

Measuring from the 12th fret to the E string, theres a 7mm gap, and from the 12TH fret to the G, theres a 5mm gap, i dont understand how to measure the relief in the kneck etc, i dont think its to tight, mabe the bridge is to low or high, but probably too low, i'm not sure, just this buzz on the E string is annoying, and the slight rattle just has me a little concerned, but non of these things happened before i put the new strings on, and before i raised the bridge slightly and mabe before i loosened the truss rod, it was all after x-mas

i've also just tryed taken all the strings off and putting them back on, and it got rid of the buzz on the G string, so i took it off G string off again and put it back on to see if it was just a flook, and the buzz was back, the rattle isnt as bad either when i pluck the E string, also, when i pick the bass up, if its lieing down, and i pick it up with the kneck, theres a little snap sound, a little click, why is this? am gunna try tighening the truss rod till i cant tighten know more, then slowly loosing it.

Are you winding the strings "down the post"?

In other words, as you wind the string, each wrap around the tuning post should be under the previous wrap around. This keeps the string pushed down against the nut.

yeah i make sure i'm winding the string down the post, so it comes off at the very bottom, mabe the grooves in the nut have warn down too far, but i've only had the bass a year, and like i say, it only started happening when i put the new strings on, and loosening the truss rod, about 1 week ago
