Gear Up for Accurate Pitch Courtesy of Gotoh
When it’s time to upgrade or replace your prized axe’s tuning heads, SD91 HAP-M locking tuners by Gotoh will serve you well for years to come. SD91 HAP-M locking tuners are manufactured in Japan by experts who draw on Gotoh’s decades of hardware expertise. Dozens of manufacturers in Sweetwater’s network trust Gotoh tuners, so you can, too. SD91 HAP-M locking tuners feature a 15:1 gear ratio and zinc buttons that add a vintage vibe to new or old equipment. What’s more, integrated HAP-M locking mechanisms combine Gotoh Magnum Lock and adjustable post technology for extra-precise control over individual string height and performance. The improved stability, reduced breakage, and better resonance of Magnum Locks make them an invaluable enhancer for guitars with tremolo or vibrato systems. HAP mechanisms grant ultra-precise accommodations for break angle adjustments that reduce tension and improve sustain without dampening the resonance of open strings. Flat peghead designs are especially primed to benefit from HAP performance, as the system allows string trees to be permanently removed and replaced with a better solution. Put guitar projects on the path to accurate pitch and performance with high-quality Gotoh hardware from Sweetwater.
Gotoh: Japan’s leading hardware purveyor since 1960
Founded in 1960, Gotoh reigns as Japan’s perpetual champion of machine head manufacturing. The company’s seeds were planted in 1950 when Masao Gotoh’s research lab began producing strings for violins. Mid-century disruptions in music technology prompted a pivot to guitar hardware, and by 1960, Gotoh was ascendant in the guitar market. Today, dozens of worldwide brands finalize instruments using Gotoh tuners, tailpieces, and beyond, arming players with reliable string performance and impeccable tuning stability. While Gotoh aftermarket parts can be difficult to procure in the United States, Sweetwater’s direct relationship offers an attractively wide range of Gotoh parts. Here, you can also find aesthetics and technical features that fuel your vision, spanning vintage-inspired favorites to modern designs.
