Hey there it is a Antoria ebo copy.I think it had the original strings on from the 70's swapped them out from a setfrom a jazz I had put new strings on any way it broke the low E ,hmm. So I saw your good self giving away some only really need one string im looking at single strings about a fiver on ebay which are shorty strings so I guess if it was from along scale bass thats why it broke and unravelled itself.
