The Tune-o-matic has been a standard for countless Gibson models for more than 60 years. Designed by legendary Gibson president Ted McCarty in 1954, the Tune-o-matic set the standard for simplicity and functionality. The Nashville Tune-o-matic offers un-notched saddles with individual saddle screw retainer clips, and a wider footing for greater intonation range. • MFSKU PBBR-045 • UPC 711106551258
