I just installed this in a 2017 Gibson Les Paul Studio. I've always played Gibsons for the wider, shorter neck scale, which fits my hands and fingers better. But I've always been frustrated with the tuning issues inherent in this design. The Tusq XL is brighter with way better sustain than the stock nut. And I can finally keep the G string in tune for a whole song! The string spacing on the Tusq XL was slightly wider, and the pre-slotted string slots are shallower than the stock set up, so hand sanding to match the height and width of the original still left my action way too high, which I compensated at the bridge. I'm no luthier, & still working to dial in the action and intonation, but it's already a huge improvement for this guitar. Recommended!
