Tuners

I'm very happy that I decided to install these machine heads. The quality, fabrication, and finish are excellent. They are much easier to use than the original factory tuners. Highly recommendable!

Excellent Machine Heads

Sillo 09.04.2025

Unbelievably easy to install and very high quality machine heads for bass. I replaced the stock heads on my Gretsch Streamliner Jet Club Bass with these in black and they look great as well as performing their job great. Highly recommended.
