bass, has suddenly developed a kind of annoying buzz.. well really annoying.. Im not sure 100 percent if this was always here of if I just managed to avoid playing that particular fret and sting all this time lol. this may sound weird, I hope im explaining it right but I started getting major bumble bee sounding buzz when I play the 8th fret (only) on the low E sting (only) but its coming form the 14th fret.... Because of the way sound travails though the wood of this particular bass I kind of had a harder time then I usually do identifying where the buzz was originating from exactly since if I put my ear closer to the bass to try to pinpoint location I could for example hear it coming from the head-stock or the back of the body or places on the neck SOOOO I eventually cut a peace of paper to small size and stick it, in-between the low E sting and frets (with bass laying flat on work bench.. ) I would hold down the 8th fret and play it and then move the paper to another fret (I did this both on frets before and after the offending area) I eventually reached the 14th fret and moved the paper there, Once again holding down the 8th fret and plucking it, and thats when the bumble bee sound was muffled by the paper muting effect.... To be sure I continued all the way down to the 24th.. but the only one that stopped it was the 14th fret. THE SHORT VERSION. I seem to have fret buzz when I hold down the 8th fret ONLY on the low E sting but its originating form the 14th fret.... If that makes any sense. bass/setup info ---4 string Sr1400E. My bass had been set up, when I bought it, and I rechecked the measurements just now -----> relief is about .4 mm, action is 2.5 on low E sting, 2.0 on G sting. sting change history --- (probably dosn't matter) Original string gauge from the factor was elixirs in .45/.65/.85/.105, But I quickly upend my gauge to .50/.65/.85/105 a week after owning the bass, and all sting changes have been constraint with this previously.. until 3 days ago when I bought some Ernie ball cobalt hybrid slinkys which match the original gauge set as far as sting thickness goes more or less. Its after putting on the new stings (my 4th time changing stings over all on this bass) that I noticed my issue, I looked closely at the stings and noticed several defects, kinks and unraveling winding, asked for my money back but was simply given an exchange and all they had was "regular slink cobalt's" left so I settled with them. But the problem persisted (this set doesn't looked defective either that I can see) so I investigated further until I found out im having fret buzz when playing the 8th fret but originating form the 14th. Previously I had chromes (flat-wounds) and before that elixirs. yea I like to peppermint with different kinds of stings on every new bass until I find the best match.
