| Sorry in advance for the long post...
So...is the only problem a little fret buzz on fretted notes (not open strings), that’s barely heard through the amp? Or is there more? How hard do you play? Where on the neck does it buzz? On which strings? Are they brand-new roundwounds (which can sound rattly until they’re broken in a bit)? Did your previous bass have absolutely zero buzz?
I'm not super-clear on when/where the buzzing is happening, but if it's only on fretted notes, that has nothing to do with the nut; fretting a note takes the nut out of the equation. And I'd say a little fret buzz is normal for most people.
A new nut installed by a pro should probably run $40-50. Along with an overall setup, maybe $75-100. You don’t want to replace the nut yourself, for a couple of reasons; based on my understanding of your description, I don’t think you need to replace it at all.
First, do you do your own basic setups (neck/truss rod adjustment, intonation, action/string height), and understand how each of these affects the other? Nut replacement is NOT the place to start when learning DIY instrument setup. I’ve done my own setups for a while now; once you understand it, a basic setup isn’t rocket surgery, but cutting a new nut (along with performing fretwork or major neck work) is something I would still take to a pro.
Second, do you have the proper tools to cut the nut slots to the correct size, shape and depth? Do you even know what those measurements are? Those precut nuts have ZERO chance of being just right for your bass straight out of the box. It would be hard to get it right, or even know where to start, without having some idea of what you’re aiming for, and the tools to get there.
Third, and most importantly, it doesn't even sound like a nut problem to me. The slightly wider nut slots should have zero effect on fret buzz; same with any bridge saddle modifications that may have been done. The only issue with the bass previously being tuned down is that it may need a basic setup due to the different string tension.
Not sure what to tell you about the action...if the bridge pieces are up as high as they will go, your bass should be almost unplayable. You may need a truss rod adjustment, as too much or too little neck relief could be a cause of string buzz. It also affects the action.
I hate to tell you to spend more money, but It might be worth it to let a pro look at it. It could be a matter of a couple of simple adjustments. |
