Aquila 320U ROUND SPIRALS 4 STRING BASS 33”/34” scale ( 84/86cm)

This set is characterized by a different construction system than usual, which uses a special aerospace-grade multifilament instead of the common nylon multifilament. Varnished copper is used for the coating, which is hypoallergenic and less noisy under the fingers.
Pure copper replaces stiffer steel, nickel and phosphor bronze: these materials have a lower specific weight than natural copper. The higher the specific weight the better the acoustic performance
