The legendary Yamaha SG model remains timeless as ever in 2023. This model is handcrafted with the utmost care and precision in Japan and is produced in small batches.  Utilizing the highest quality components, the SG1820 is an instrument for the discerning player who truly values tone and craftmanship.
  • Body Material / Structure

    While preserving the basic structure of Maple Top/Mahogany Back and SG’s iconic double cutaway design, the body of SG1820 was redesigned to capture the sound and look which today’s guitarists want.. The contoured body top curves more deeply than previous models - the top arc of the curve, the center part of the body, has optimized wood-mass to maximise string-body vibration from the from the bridge and tailpiece. The deep curve maintains the guitar’s optimum weight balance and enhances the SG’s stunning shape.. The back contour featured on SG1/2/300, designed for increased comfort when the guitar was played high on the strap, has been modified to a flat back on the new SGs. The new flat back design increases the volume of Mahogany to significantly increase the low-mid response and presence while reflecting ergonomics needed for the lower stance modern players take with SGs.

  • Fingerboard

    With countless custom-shop artist-spec SGs being produced with Rosewood fingerboards instead of the traditional SG’s ebony board, we selected premium rosewood for the fingerboard on the new SGs. A warm, well-balanced tone and great feel match modern tones and playing styles perfectly.

  • Headstock

    The SG’s headstock has been reshaped to a slightly smaller size to improve body balance. The classic ‘flower pot’ head mark has also been down-sized to match with the new headstock size.

  • IRA(Initial Response Acceleration)

    If you've ever played another guitarist's instrument and not been able to get the same sound, it's probably because you are playing a different style than what the guitar is used to. After playing the same guitar for years, the guitar adapts to the guitarist's playing style. It takes time for a new guitar to adapt to your own way of playing. Stress found between parts like finish, woods, body, neck, fingerboard, nut, bridge, etc., must be released before all of the parts can resonate together as an instrument. It takes time and a lot of playing for this to happen.. Using IRA technology, stresses like those between the finish and wood are release by applying specific vibrations to the completed guitars. Once this treatment is complete, the guitar responds accurately to the guitarist's performance, and produces sound more easily. It also shortens the time needed for the guitar to adapt to your playing style. And it delivers excellent sustain.

  • Pickups

    *SG1820: Seymour Duncan ‘59. A classic, warm humbucker with smooth midrange and rich high-end. Works perfectly with SG1820 to give a hot-vintage tone with plenty of presence and depth.

  • Grover Locking Tuners

    The SG’s strings are locked in place at the post to ensure zero slippage and complete tuning stability along with quick, efficient string changes.

  • Tonepros Bridge / Tailpiece

    Tonepros’ lighter bridge and tailpiece design enhances the vibration of the guitar’s body by reducing the mass of the metal parts. The locking design ensures the bridge and tailpiece are tightly anchored on their mounting studs for ultra-efficient vibration transfer, maximizing sustain and improving clarity.

  • Graph Tech Nut

    Graph Tech captures the best properties of bone nuts - exceptional resonance, amazing clarity and smooth sustain - while improving on them with permanent lubrication, better longevity and easier cutting.

  • Control Knobs

    Control knobs on all three models complement guitar designs.
