Higher action required for Trubass 88 to avoid fret buzz?

[markdavid]

Hi

Have just tried Rotosound Trubass on one of my basses, I was really pleased to find that this bass that is usually a little out with intonation is now strangely pretty much bang on however I have found that there is fret buzz at 12th and 15th fret of the A and D string that is not there with other strings, is a little annoying but I can live with it as I rarely go that high on the neck.

Have tightened the truss rod but has made no real difference, I remember reading somewhere ages ago about fret buzz with Rotosound Trubass , does anyone here have this issues with these strings and have to raise their action to resolve this?
My action is a hair above 2mm on the E string and slightly under 2mm on the G, I may raise the action slightly to counter the buzz but really hoping I dont have to raise it too much

Tightening the truss rod will straighten the neck and make buzz worse.

If it's just 2 specific frets on one string it sounds like you have worn your frets down there.
Might be time to have some fret levelling done.

Sounds to me like you just need a proper setup done, which is isn't uncommon especially when changing to different strings.

The reason I tightened is that usually buzz on the upper frets means there is too much neck relief

I have them on my MIK Rogue VB-100; no problem with them whatsoever. However... when the bass' neck is straight as possible, all the frets are level, too. Sounds like that might not be the case with your bass...

Try and loosen the truss rod a quarter and see if that helps. then you may be able to lower saddles.

For buzz high up the neck, you need to raise the saddles, tightening the truss rod will make buzz slightly worse especially for lower frets.

Having buzz with a different set of strings is not a string issue, it's a setup issue, unless a set of strings is identical to before you always need to adjust the setup (truss rod, saddle height and saddle intonation) even if it's a different brand of the same gauge. These nylonwounds are larger gauge to compensate for lower density, but may be lower tension than your previous strings, so a higher action is necessary.

Or maybe nylon tape is not as consistent as metal windings.

Sort of, neck relief alters the balance of low-fret buzz against high-fret buzz, but straightening a neck creates more buzz everywhere so you still need to raise the saddles as well.

Thanks for the replies, I think I will try loosening the truss rod slightly, I suspect that the Trubass are lower tension than the previous strings and the fact that the action was about 0.3mm lower after the string change suggests the same
