This nut is for a string spacing of 1-3/8". Epiphone Les pauls have a string spacing at the nut of 1 3/8". USA Gibson Les Pauls have a string spacing of 1-7/16". That 1/16" makes a difference. You make sure you get the right one. The string spacing on this particular nut is 1-3/8" which will also fit an ESP LTD EC series guitar. Graph Tech does make an exact fit for a 1-7/16" Les Paul nut. These are good quality. **Q: Will this fit Ibanez Gio guitar? If not can a nut be recommended?** A: It needs to match the neck radius and the string width. Measure those two things and if it matches this nut then it should fit. To measure the radius I just made a template from cardboard. Height wise this nut has plenty of stock to be fit to any neck. I think I ended up sanding about 1/8" off the bottom to fit it to my Yamaha se350 (strat style guitar). **Q: Will this fit a Jackson js22 dinky ?** A: Whatever nut you decide on, some adjustment will be needed. If you don’t have the tools to do it, bring to a luthier. If you do decide to do it, you will need a caliper and some files. Good luck. **Q: Is this for a right-handed guitar?** A: Yes ## Frequently Bought Together - GRAPH TECH GUITAR LABS Guitar Top Nut (PT-6643-00) - PRS Guitars SE Locking Tuners Set of 6, Chrome (106297::C:003) - Graphtech Stringsaver Saddle Prs -6pcs --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/6577707-tusq-xl-by-graph-tech-pt-6643-00-nutfits-schecter](https://www.desertcart.vu/products/6577707-tusq-xl-by-graph-tech-pt-6643-00-nutfits-schecter) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-07-18*
