I have switched the pins in my 2010 Epiphone Texan from the stock ones that came in it to some made by Planet Wave's, I believe they are some sort of wood. The old one's where plastic I'm sure, it has a brighter tone than before. I'd like to replace the nut & bridge as well and the first 4 or 5 frets to but I don't know if I should go with bone or ivory. It's not an old guitar but as it's my only use-able one atm so I have played it a LOT in the short time I've owned it from new.
