Alvarez AU70WB-6 Artist 6-string Baritone Uke Size Travel Guitar Nylon Alvarez Ukuleles have been carefully designed to deliver an open sounding and responsive instrument with good projection, volume and fine tone.  All Alvarez ukes are constructed with a dovetail neck joint for optimal strength and transfer of energy between the neck and body. The bracing design is a modification on traditional fan style braces to optimize response. The response is also aided by a solid “slotted” rosewood bridge, which enhances projection and helps to make string changes easier and quicker.  Other appointments and features include quality-seasoned tonewoods, real bone nut and saddles, mahogany neck, rosewood fingerboard and premium tuners.  Alvarez Artist ukuleles are lively and sophisticated and deliver exceptional player experience.
