No getting away from it, the string angles between nut and tuners on a Les Paul are not optimised for tuning stability. I've had days when the f**ker just won't stay in tune. This device fixes the issue at a stroke. The V1 is the one you need for a Les Paul with Kluson type tuners (push in ferrules, no nuts). Simply replace your truss rod cover with this device. It takes 5 minutes to fit but potentially will fix years of 'out of tune' frustration. I'm lucky enough to have 3 Gibson's, they're all now fitted with String Butlers, just wished I'd known about them years ago.
