Gibson is failing me big time! i have 1 new 2015 les paul traditional, and 3 second hand. i like these guitars. except the brass nuts, they wear out and my strings start breaking. I asked 2 titanium nuts last year for 2 second hand guitars. they were sent no problem. now i ask 2 other ones for 1 new and the other second hand guitar. gibson mails me: sorry but we don't replace nuts for second hand guitars. best of all, it's the same customer service person !!! so i'm buying a lot of gibson guitars. and the parts they KNOW don't work, they don't wanna replace them. fail !!!! thanks a lot gibson. this is really really BAD customer service. so people, beware!
