This listing is for a set of custom made 41" La Bella Flat Wound Bass Guitar Strings. I custom ordered a few dozen of these directly from La Bella. I own a few Ampeg Devil bass guitars and could never find strings for it. La Bella agreed to make me these extra long 41" strings but I had to order a few dozen so I have more than I need. The strings are flat wound Deep Talkin flat wound strings .045 .065 .085 .105 gauge. Please look at the pictures and email with questions. The strings come as pictures and are in sealed packages. Please let us know if you need more than one set.   Thanks for looking,,
