Since its debut in 1974, the Yamaha SG has been the choice of some of the most influential guitarists. From its rich tone and long sustain to its outstanding playability and stunning design, all of its signature characteristics have stood the test of time, remaining relevant to this day. However, there have been countless changes in the music scene and the emergence of many new music styles since the birth of the SG guitars. The SG1820 series has been designed with this in mind featuring a refined, modernised, no-compromise specification to make them perfect for today’s musicians Finally, the stadium-ready SGs that Yamaha have been producing for artists are available to the public.

Body Structure
While preserving the basic structure of Maple Top/Mahogany Back and SG’s iconic double cutaway design, the body of SG1820 has been redesigned to capture the sound and look which today’s guitarists want. The top arc of the body curve 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 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.

Custom Pickups 
Featuring Seymour Duncan '59 pickups, the SG1820 delivers classic, warm humbucker tones with a smooth midrange and rich high-end. Works perfectly to give hot-vintage tone with plenty of presence and depth.

Electronics 
Super-premium electronic parts are selected for the new SG guitars only after meeting Yamaha’s exhaustive testing criteria. Using the finest switches and pots, the same as those chosen by pro guitar techs on stages all over the world, means that you can step on stage night after night confident that all of the little details are taken care of.

Hardware 
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. Grover Locking Tuners lock the strings in place at the post to ensure zero slippage and complete tuning stability along with quick, efficient string changes.
