Allparts TK-0974 Schaller 6-in-line Black Staggered Locking Tuners

Schaller's 6 - in - line staggered locking tuning keys come in a sleek black finish. Each tuner has a 16:1 gear ratio and needs a 10mm (13/32') - diameter mounting hole. The staggered posts are designed to optimize string tension. They're positioned higher for the E, A, and D strings and lower for the G, B, and high E strings. This unique design creates a steeper string angle off the nut, which greatly improves tuning stability and reduces string slippage. Mounting screws are included.

Using these Schaller locking tuning keys is easy. First, make sure you have a 10mm (13/32') - diameter mounting hole on your instrument. Then, attach the tuners using the included mounting screws. When you're tuning your strings, turn the key slowly to get the right pitch. Remember, the staggered design helps keep your strings in tune better. For maintenance, keep the tuners clean. You can use a soft, dry cloth to wipe off any dust or dirt. Avoid using harsh chemicals as they might damage the black finish. If you notice any string slippage, check that the tuners are properly tightened and the strings are securely locked.
