I have one set of EXL-165, 4 string left. Some were purchased in the twin pack set, and the box has been discarded, so the strings are in the sealed plastic bags, but all are brand new. All long scale. I have decided to use D'Addario steel strings, and no longer have a 4 string bass, so that's why I am selling them. $10 per set shipped to the USA. $8 each for multiple set purchases.
