- Hi, I bought this LP brand new in London '71, as is . It was a new delivery and had been in the shop 2 days and hung on the wall along with a Custom BB .I am trying to sell this guitar at the moment and I'm getting a lot of flak about these plastic rings around the Tailpiece studs which were on there when I bought it. I'm being accused of tampering and covering up .Has anyone ever seen this or can explain these rings .I've looked at thousands of photo and never seen them on another LP. Did Gibson change bridge/tailpiece suppliers at any time due to shortages and were the guitars already prepped for components that had a different Spec to the new supplier ??? Appreciate any help . I contacted Gibson and got a Don't Know and await a reply from Gruhn NY .
