Part of Yamaha s L Series the LL16RD features all-solid rosewood back and sides with a hand-selected premium Engelmann Spruce top. A newly designed bracing pattern and A.R.E. treatment create rich warmth and open resonance while maintaining excellent tone balance. In addition a new comfortable neck profile and Yamaha s Zero impact pickup ensure you a stress-free performance on stage. A.R.E. (Acoustic Resonance Enhancement) A.R.E. is an original wood reforming technology developed by Yamaha. Through precise control of temperature humidity and atmospheric pressure the molecular properties of the wood can be manipulated into a more acoustically ideal condition similar to the molecular characteristics of woods in instruments that have been played for years. New Designed Bracing Pattern A modified non-scalloped bracing design retains the L series characteristic bright tone while enhancing low-end tone. High Comfortable Traditional Neck Profile A reevaluation of string spacing string height fingerboard binding and neck taper led to a new neck shape that better fits today s traditional players. The new design offers stable grip and smooth playability over the full length of the neck. 5-Ply Necks The 5-ply neck of mahogany and rosewood designed with a volute at the headstock plus a double action adjustable rod creates a neck with excellent strength and stability. SRT Zero Impact Pickups The SRT Zero Impact Pickup system is a newly developed passive type pickup configuration designed to minimize the pickup s impact on the tone and traditional appearance of the instrument. The system utilizes individual piezoelectric elements for each string to faithfully reproduce the dynamic sound of the L Series and give the instrument outstanding presence when playing in a band.
