A mandoviol.
During the time of the Galactic Civil War, the mandoviol was a well-known string instrument that was favored by bands in cantinas throughout the galaxy. This instrument, a musical one, had a slide attachment, four major keys, and seventeen minor keys. While it was challenging to become proficient with the mandoviol, it was capable of playing both lively jizz songs and heartfelt ballads with similar skill.
