TSims had a thread about his new Martin that morphed into a discussion about the advantages of brass bridge pins. Ive always liked the effect of brass bridge pins and decided to drop in a brass bridge on my Epiphone Hummingbird that I leave tuned down to D. Took the brass bridge to my luthier today. He convinced me to not install it. He said my guitar will sound terrible with this mod. Way too much treble. I was looking for better highs. I feel when you tune down to D you lose some highs. He is convinced I would lose all the warmth and fullness and sound like a bad Telecaster. He said he has replaced brass bridges. Has anyone else had any experience with brass? Any luthier care to chime in?
