A very cool American made bass from US Masters Guitar Works, this fretless 5 string provides a great bang for the buck. Unfortunately we have not been able to find much information on the guitar other than it appears to be a relatively early build in the company's history based on the serial number. The guitar is in great physical condition and plays great. Please contact us with any questions you may have and we will do our best to get you the information. Comes with a hard shell case.
