Precision performer Gibson parts advertisement, promoting the TP-6 fine-tuning tailpiece. The ES-347TD had been fitted with the TP-6 from around 1978.
Around this time Gibson were starting to really promote the spare/replacement part side of their business, offering pickups, bridges, and tailpieces as suggested upgrades for their own and other brands guitars.
Larry Carlton doesn't settle for anything less than the best. And you shouldn't either. The Gibson TP-6 fine tuning tailpiece gives you performance perfection, in concert or in the studio, with fingertip ease. For the first time you can fine tune with one hand while you are playing. And you don't have to won a Gibson to get the benefit of precision tuning at the touch of your fingers as you play. Because Gibson designed it to fit most instruments with a stop bar tailpiece.
