This is the KALA KA-15S's specification

Introducing the Kala KA-15S Mahogany Soprano Ukulele. The KA-15S has mahogany sides, back, and top. With its all-mahogany construction, this soprano produces a bright, warm tone with enough volume to be heard while playing with a group. A satin finish gives the KA-15S an antique, well-played appearance. This guitar has a low action and is easy to play. Die-cast tuning machines complete this attractive set.
