The Alvarez Artist Series AJ80CE-12 Jumbo has a solid A+ Sitka spruce top, hand selected from quarter sawn wood paired with a maple body for a brighter tonal blend. As with all Artist Series models it's designed to get the best out if its components, and for them to work together to produce a tone and player experience rarely found in affordable instruments. These components include Alvarez's FST2M bracing system, bi-level bridge, real bone nut and great quality tonewoods. FSTM is a forward shifted X brace design. Both the X braces and asymmetric tone bars are scalloped.
