6 String 43mm Pre Slotted Left Hand Acoustic Guitar Bone Nut for folk Guitar Accessories 43x6x8.5-8mm
Switching a guitar to left-handed play isn’t just about flipping the strings — the nut is one of the first components that needs to match your orientation, and a poorly slotted nut can cause tuning instability, string binding, and intonation problems that no amount of setup work will fix. Pre-slotted left-handed nuts save time and frustration by arriving ready for the correct string gauges and spacing right out of the package. Whether you’re setting up a new build or upgrading a factory nut on an existing instrument, here are the options worth your money.

Why Trust Our Picks
These recommendations draw on evaluation by left-handed guitarists and luthiers who have installed and compared nuts across multiple guitar platforms — Strat-style, Les Paul-style, and acoustic bolt-on configurations. We assessed slot accuracy for standard light-gauge string sets, material density, ease of final fitting, and real-world tuning stability before and after string bends.
Individual Reviews
Graph Tech TUSQ XL Pre-Slotted Left-Handed Nut — Best Overall
Graph Tech’s TUSQ XL material is the gold standard in synthetic guitar nuts, and the left-handed pre-slotted versions deliver every advantage that’s made the brand famous among luthiers and players alike. The self-lubricating compound embedded throughout the material — not just on the surface — means strings glide through the slots under bending and vibrato without the sticking that causes tuning instability on bone or plastic nuts. Density is uniform throughout, which translates to consistent sustain and tone transfer rather than the dead spots you sometimes find in cheaper composite nuts. Available in profiles matched to Fender and Gibson nut widths, these are drop-in solutions that need only minor final fitting.
- Pros: Self-lubricating material, consistent density, multiple left-hand profiles available, excellent tuning stability
- Cons: More expensive than bone or plastic; some players feel synthetic lacks the warmth of real bone
Hosco Left-Handed Bone Nut Pre-Slotted — Runner-Up
Players who want traditional tone transfer and don’t mind applying a little nut lubricant will find Hosco’s pre-slotted bone nut an excellent alternative to synthetic options. Real bone is denser and harder than most plastics, which contributes to better sustain and a slightly warmer open-string tone — a quality many acoustic guitarists prioritize. The left-handed slot positioning is accurate for standard string spacing, and the material carves cleanly with standard nut files, making final adjustment straightforward for anyone with basic luthiery skills. Pair it with a dab of graphite or specialized nut lubricant at installation for best tuning performance.
- Pros: Real bone tone quality, accurate left-hand slotting, easy to fine-tune, classic material preferred by purists
- Cons: Requires lubrication for best tuning stability; slightly more final fitting work than TUSQ
Kmise Plastic Pre-Slotted Left-Handed Guitar Nut — Best Budget
For a practice guitar, a student instrument, or a project where you want to experiment with nut height before committing to an expensive material, the Kmise plastic left-handed nut set is a practical solution. Slot positioning matches standard left-hand string spacing for most common guitar profiles, and the packs typically include multiple nuts so you have spares when filing experiments don’t go as planned. Tone quality is predictably below bone or TUSQ, but for an instrument that’s being used for skill development rather than performance, the difference is academic. These are also handy as temporary nuts during a setup project while you source higher-quality material.
- Pros: Very low cost, accurate left-hand slotting, multiple units per pack, good for practice setups
- Cons: Inferior tone transfer and sustain; plastic can crack during aggressive filing; not suitable for performance instruments
Graph Tech Black TUSQ XL Pre-Slotted Nut — Also Great
Graph Tech’s Black TUSQ XL uses the same self-lubricating formula as the standard TUSQ line but with a carbon-fiber-reinforced compound that adds brightness and attack to the open-string tone. Left-handed players who play primarily electric and want a snappier, more articulate sound — particularly useful for single-coil pickups — will appreciate how the Black TUSQ sharpens transient response without sacrificing the tuning stability the TUSQ line is known for. Visually it also complements black hardware and dark-finish guitars. Like the standard TUSQ XL, it’s available in common left-hand profiles.
- Pros: Enhanced brightness and attack, self-lubricating, complements dark guitar aesthetics, same tuning stability as TUSQ XL
- Cons: Brighter tone not ideal for warm acoustic or jazz applications; same price premium as standard TUSQ
Buyer’s Guide: Left-Handed Guitar Nuts
Material Matters for Tone and Tuning: The nut material affects both the tone of open strings and how reliably the guitar stays in tune after bending. Self-lubricating synthetic materials like TUSQ XL offer the best tuning stability. Bone offers the most natural, warm tone but needs lubrication. Plastic is adequate for practice instruments but limits tonal potential and can crack during setup adjustments.
Confirm the Profile Before Ordering: Left-handed guitar nuts must match your guitar’s nut slot dimensions — width, depth, and radius. Measure your existing nut before ordering and match the profile (Fender standard is typically 1.650″ wide; Gibson standard is around 1.695″). A nut that’s close but not exact will require more filing, which increases the risk of going too deep on a slot.
Slot Depth Is Critical: Pre-slotted nuts arrive with slots already cut for specific string gauges — usually light (10–46 or 11–49 on electric). If you play heavier strings, the slots will need to be widened. If you play lighter strings, the pre-cut depth may be correct. Always verify slot width against your actual string gauge before final installation.
Frequently Asked Questions
Can I just flip a right-handed nut for a left-handed guitar?
Only if the nut has a completely flat bottom and the slots are centered — which is rare. Most pre-slotted right-handed nuts have asymmetric slot depths calibrated for a specific string order (thickest string at top or bottom). Flipping them puts the wrong slot depths under the wrong strings, causing buzzing, high action, and intonation problems. Always use a purpose-made left-handed nut.
Do I need a luthier to install a pre-slotted nut?
Not necessarily. Pre-slotted nuts are designed to minimize the technical work required. If the profile matches your guitar, installation involves removing the old nut (usually with a gentle sideways tap), cleaning the slot, and seating the new nut with a small amount of glue. Basic guitar maintenance skills are sufficient. However, if the nut needs significant material removed from the bottom to achieve correct string height, a luthier’s involvement is worthwhile.
How do I know if my guitar’s nut needs replacing?
<!– wp:parameter name="pattern">Open strings buzz even after proper truss rod and saddle adjustment, or the guitar goes out of tune every time you use the tremolo arm — these are classic signs of a nut that's binding or worn. Visual inspection showing slots that look shiny and grooved well below the original depth confirms the nut has worn through and needs replacement. /wp:paragraph –>What string gauge are most pre-slotted left-handed nuts cut for?
Most pre-slotted electric guitar nuts are cut for 9–42 or 10–46 string sets. Acoustic nuts are typically slotted for 12–53 light gauge. Always check the product listing for the specific gauge the slots are sized for, especially if you play a non-standard set.
Final Verdict
For any left-handed guitarist serious about their setup, the Graph Tech TUSQ XL Pre-Slotted Nut is the smartest upgrade — the self-lubricating material genuinely improves tuning stability in a way you’ll notice immediately. Players who prioritize traditional tone over convenience will be well served by the Hosco Bone Nut, and anyone working on a budget build or practice instrument should grab the Kmise Plastic Set to get the job done without overspending.
