Hi, I recently acquired a used Ibanez BTB676. As expected, It is not brand new (some minor scratches here and there). One of the most relevant issues (for me) is the condition of the monorail bridges (tuning machine are not much different but I can live with it). Its finish is somehow deteriorated (the specs for the material are unknown for me but the fact that it is a 2BB1MR2K-Mono-Rail II Bridge, Color = Cosmo Black, which is actually something like a flat metallic finish). The units are sold separately @ ~ $26 USD... not bad. I don't know if replacement is due (I mean, the bass tone is outstanding as per my limited sound color palette). If so, I would like to change to a black finish... Does anybody know if there are black replacement units for these Rails? Thanks in advance!
