From Aquila:
Vibrating length: 42-43 cm
The classic A-tuned Guilele/Guitalele set, suitable for all instruments with vibrating lengths of 42-43 cm (17′′).
Consisting of Nylgut® cellars and silver copper spun basses on Nylgut® cores, this set provides a warm, rounded sound, with excellent attack readiness and acoustic projection.
Attention: unlike classic nylon, Nylgut® is a shear-sensitive material. Before assembling the strings, make sure the grooves at the nut and bridge are shallow, perfectly smooth, and free of sharp angles.
