Don’t hesitate to get in touch with our team!

Yes. A standard right hand guitar generally has its tuning machines on the left side (would need 6R Right Hand tuners), while the reverse headstock of a standard guitar would have a headstock that usually seen on a left hand guitar (tuners on the right side), so you should choose 6L Left Hand tuners.

To determine the right size or fit for a specific accessory, we recommend referring to the product descriptions or specifications, as they often include information about compatible instruments and sizing details. Additionally, you can reach out to our customer support team at [support@guyker.com] for assistance. We can provide guidance and help you find the appropriate accessory for your guitar or bass.

At Guyker, we prioritize the use of high-quality materials to ensure the durability and performance of our products. While the specific materials used may vary depending on the accessory, we commonly utilize materials such as:

■ Woods: Some accessories, like guitar knobs or picks, may be made from various types of wood, including rosewood, ebony, or maple.

For more detailed information about the materials used in a specific product, we recommend reviewing the product descriptions or reaching out to our customer support team at [support@guyker.com] for further clarification.
