VANSON Pre-Slotted 42mm Bone Nut for Stratocaster or Telecaster type guitar
The easiest and cheapest way to improve the tone on your instrument is to start with the strings breaking points, i.e. the nut and then the saddles/bridge.
Bone is renowned to be the best material to retain your guitars natural tone, allowing for a better attack and greater sustain. Master luthiers, and professional musicians swear by it, and you 'll notice it's saved for brands' Custom Shop and Deluxe models, even though it's cheap enough for them to put it on all their guitars.
Our nuts and saddles are a high quality dense bone that are precision cut and polished, the grooves will be smooth and clean enough that you'll have no problems at all with tremolo work.
Yes there are a lot of alternatives on the market these days, but the marketing teams have to make their money too, so there will always be the next best thing, but most will go back to bone eventually.
