Fit was spot on for my guitar and it was straightforward to install with minimal effort. Once fitted, the difference was immediately noticeable. Tuning feels more stable and overall tone sounds clearer and more consistent, especially when using the trem or doing bends.Build quality feels solid and it does exactly what it’s meant to do without any fuss. Simple upgrade, easy to fit, and genuinely improves how the guitar feels and sounds.If you’re looking for a quick, effective upgrade that actually makes a difference, this is well worth it. ### ⭐⭐⭐⭐⭐ One of the best, for about a tenner *by on Reviewed in the United Kingdom 12 November 2025* I got this for a PRS Custom 24. It fits perfectly, is solid, and a huge upgrade for your guitar for almost no money.It's also fairly easy to install, not that that is specific to this nut, but it's a 20 minute job that's easy to do. ### ⭐⭐⭐⭐⭐ Great nuts! *by on Reviewed in the United Kingdom 6 December 2025* Fits my ibanez rg421ex perfectly. There a bit pricey but probably worth it as there good quality nuts that don't need any extra work other than sanding the bottom for the right height. I would recommend these nuts! ## 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.at/products/48651070-black-tusq-xl-by-graph-tech-nut-6-stringg-electric](https://www.desertcart.at/products/48651070-black-tusq-xl-by-graph-tech-nut-6-stringg-electric) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-08-22*
