Every bass player knows that moment when you're mid-gig and your bass goes slightly out of tune. It's frustrating, distracting, and can ruin the groove. That's why investing in quality tuning machines isn't just about convenience – it's about ensuring your instrument always performs at its best.

Engineered for Precision

These Guyker bass tuners feature a remarkable 17:1 gear ratio, meaning each full turn of the tuning key moves the post just enough for micro-adjustments. You'll find yourself tuning faster and more accurately than ever before. The precision-machined gears eliminate the slop and play that plague cheaper tuners, giving you the confidence that your tuning will stay locked in throughout your performance.

Built to Last

What really sets these tuners apart is their sealed design. Unlike open-gear tuners that collect dust, grime, and sweat, these sealed units keep lubrication in and contaminants out. The cast aluminum housings provide solid construction that won't flex or bend under tension, while the metal knobs give you a solid grip even with sweaty fingers. No more slippery plastic knobs that round off or slip when you need them most.

Perfect Fit for Your Bass

With a standard 13.7mm peg hole diameter, these tuners are designed to fit most jazz bass and precision-style instruments. The package includes all necessary mounting hardware – screws, bushings, and washers – so you have everything you need for a clean installation. Whether you're upgrading an old bass or building a new one, these tuners provide the reliability and performance that professional musicians demand.

From the recording studio to the live stage, precision tuning makes all the difference. These tuners aren't just replacement parts – they're an upgrade that will transform how your bass feels and sounds. Once you experience the smooth, precise action of quality tuning machines, you'll never want to go back.
