Used Bigsby B6 Vibrato Tailpiece 1960's (original)

The 1960s Bigsby B6 is the "cadillac" of vibrato tailpieces. If you’re looking at a classic deep-body hollow-body guitar from that era—think a Gretsch 6120 or a Gibson L-5—this is likely the piece of hardware providing that signature shimmer.

Unlike modern "licensed" versions that use die-casting, 60s units were sand-cast. This gives the metal a slightly granular, pitted texture under the polish.
