i play a thineline tele with a bone nut installed. as i remember correctly when i had it first cut by a guitar tech, it was at a pretty decent height. now it is 8 months down the line and i feel that the grooves are being eroded down such that i am having buzz on open strings. it may be that i mainly use 11s. i have a feeling that bone erodes faster over a period of time especially when you use heavier strings and are constantly changing strings week on week. a luthier friend of mine said that is why most of the boutique strat makers prefer tusq as the nut tends to stay and doesnt erode like how bone does due to the brittleness of the material. oipnions?
