I've made 3 brass nuts for my les pauls, and I don't like 'm. they grab the strings, even when they're cut liberally and lubricated with graphite powder. they sound rather bright to my ears,, and you get a lot of buzzing around. like fretbuzz, but a little bit less bad, I'd say. i changed them for graphtech's all over. Result?! awesome! the tone is more even, binding goes easier, the harmonics squeel better. its a little less bright, which I liked about brass, but overall, graphtech is for me the way to go. oh, and MUCH less tuning issues! well worth the 6.7 euro's, excluding shipment.
