Does anyone know what metals they used to make the bridge/tailpieces/studs at the time? I have a 99 r9 with the stock tailpiece and bridge setup and it sounds amazing. My used 01 r7 came with a lightweight aluminum tailpiece (the one on the 99 is noticeably heavier) and tonepros bridge. This combo makes the r7 way brighter which I'm not liking and I'd like to get it sounding closer to the 99 as possible.
