I've just received and fitted the Faber Aluminium bridge. For those interested here are my initial impressions over the Gotoh stock zinc tailpiece. Same strings were used in the interests of continuity:-
Much lighter, probably a 3rd of the weight of the stock bridge
Nicely made and nice matt finish
Slightly woody with more acoustic zing
Lighter, less full mids
quicker attack
Overall a more vintagey (based on the old 335's ive played), airy semi tone all though the difference is not night and day. Some may prefer the fuller sounding tailpiece.
