My apologies if anyone’s offended by resurrecting a “zombie thread”, but I just purchased a new set of LaBella LTF’s for a 34 year old ‘57 Pbass Fender reissue and guess what? The D string buzzes like a wasps’ nest (real bad sitar) from frets 1->19, just like some have noted on this thread.
The neck is straight with a little relief, the action more than reasonable, I’ve checked for string twist and there is none.
I will now contact LaBella in hopes of getting a replacement D string sent. (Too bad, because the other 3 strings sound totally dope!)
I don’t know if it matters, but this new set of LTF’s has the colored ball ends…. The older set of LTF’s that is STILL on my ‘62 Pbass (as I’ve mentioned earlier in this thread 2 years ago) still sound and feel great.
Let’s see what happens .
Check to see if the winding at the ball end is barely touching the spring for the intonation adjustment screw.
I've read about the metal to metal contact between the spring and the string being the cause of the high-pitched buzz, aka sitar effect.
