Independent shopping perspective
The Korena take
The gold 3+3 Vintage Deluxe 133 set pairs keystone buttons and a vintage look with a worm-and-gear mechanism designed to prevent backlash and slippage. Self-lubricating housings and the 15:1 ratio support controlled tuning operation. Its 11/32-inch post hole, 22 mm post length, and .074-inch maximum string gauge provide concrete installation checks. Bushings and screws are included for the stated drop-in replacement of 505FV or 533-series tuners.
