Thank you all for the replies!
The guitar in question is my LTD EC-401. It's a great-sounding guitar, but it is abnormally light. Somehow, it still manages to sound fatter and chunkier than my full-thickness heavy PRS SE, but I still wouldn't mind to fatten it up a bit more. Another big part of the reason why I want to change it is for it to balance better. It's not
terribly neck heavy, but it could be better. I swapped the tuner buttons to light plastic ones, and it's a lot better, but I wonder if the brass tailpiece would help here to distribute more weight onto the body.
The bridge and tailpiece themselves right now are nothing fancy like a Callaham, ABM, or Faber, but they are Schaller, so they're more than OK, I think. The bridge, I was told by emailing Schaller, has brass saddles and a zinc body, and the tailpiece is zinc. I prefer the tone of zinc over alluminum in the comparisons I hear, because it's darker and fatter, the way I'd expect a mahogany guitar to be. I wonder if brass would be even fatter-sounding and heavier in weight than zinc. It would seem so, right?
I'm looking into the Philadelphia Luthier Tools tailpiece, and it seems nice. Also the Kluson one. But how about saving a few bucks with this one? Has anyone tried it? Or am I cheaping out?
