I have a Gibson Thunderbird that I bought used. It has a stripped tuner on it. I called Gibson and asked for a contact at Grover so that I could replace the tuner with their lifetime warranty. He asked if I was the original owner and of course I said no. He said that it would not be under warranty. I told him that I figured as much and wasn't asking Gibson to do anything except tell me how to get in contact with Grover. He said that he didn't have and couldn't get that information for me. He suggested I buy another set of four tuners and use one of those. I called back and asked for the accounting department. A friendly woman answered the phone. I told her that I needed to get a hold of Grover and was hoping she had their number so I wouldn't have to get a hold of someone in purchasing. She looked it up and gave me their number and address. Grover told me "No Problem" so I am going to mail it to them for a replacement. I've never had a problem getting information from any company before this. Apparently, if you don't buy it new, you ain't nobody. Is Gibson always like that? I bought a new Les Paul, but I haven't had any problems with it.
