Frequently Asked Questions

Q: What guitar models are compatible with the B2/B3/B4 locking tuners?

A: These locking tuning pegs are designed for electric guitars using B2, B3, and B4 tuner configurations. They are intended to replace standard tuning machines on many popular electric guitar styles. We recommend measuring your existing tuner peg hole diameter and spacing before purchasing to confirm compatibility.

Q: Do locking tuners really help with tuning stability?

A: Yes — locking tuners significantly improve tuning stability by clamping the string directly at the post, eliminating the excess string windings that are a common source of pitch drift. This is especially beneficial for players who use tremolo/whammy bar systems or perform aggressive string bending techniques.

Q: What finishes are available and how do I choose?

A: These locking tuners come in Black, Silver, and Gold. To maintain a cohesive look on your guitar, match the finish to your existing hardware — for example, if your bridge and strap buttons are gold, go with Gold tuners. All three finishes are made from the same durable stainless steel and metal construction.

Q: How difficult is it to install these locking tuners?

A: Installation is straightforward for most compatible electric guitars. Typically, you remove the existing tuning pegs, insert the new locking tuners through the same holes, and secure them with the provided hardware. No major modifications are required for most standard headstock configurations. If you're unsure, a local guitar technician can install them quickly and affordably.
