From Pete 5.0 out of 5 stars Game Changer!!! November 28, 2018 Colour: BlackV3 Verified PurchaseMy 2017 Les Paul Faded T wouldn’t stay in tune for 2 minutes. After a pro setup, nut slot filing, pencil shavings and various lubricants I was ready to either sell it or smash it against the wall. Good reviews online so I took a chance. So glad I did. Installation took 10 minutes and it was like night and day. Staying in tune even with brand new strings. I was so impressed I ordered another one for my SG the next day. Great product and great service from Dan at In Tune Guitars who got back to me right away to answer my questions. Highly recommended.
