All Alvarez ukuleles are built with a dovetail neck joint for optimal strength and energy transfer between the neck and body. The bracing design is an improvement over traditional fan bracing for optimised response. This response is also supported by a solid slotted rosewood bridge, which improves projection and helps make string changes easier and faster. Additional features include high-quality seasoned tonewoods, real bone saddle and bridge inlays, a mahogany neck, rosewood fretboard, and premium tuners.
