So, I bought a Thumb 5 B.o. off of ebay that was described as mint. I got it today and externally, it is pretty close to mint, but I played it and it played like garbage, so I was going to adjust the truss rod, but the truss rod has been completely stripped. So I explain the situation to the seller and he says that it is covered under warranty, send back and he will get it fixed. HERE is the question: I am 90% sure that is not warranty work, and anyhow, can they even replace the truss rod? Do you think demanding a refund is reasonable, and likely? Thank you
