Got these to replace some "not so good" machines on a used bass. Smooth and lightweight too. There is a reason all the top builders use these machines.
The real McCoy! A must for neck diving bass. I installed a set on a Warmoth jazz copy which neck was a bit heavy and it simply rebalanced the whole instrument. Highly recommended!
Best tuners in the business. And Bob Sperzel was one of my buds. We'd use his at CertainBass except I could never get him to make the bass tuners big enough. The Ultralite surpassed you, Bob, sorry!
I have a set of these tuners that came standard on my Birdsong bass. They are solid, tight, and very stable. They are also so light (combined with the short-scale instrument design) that I have no neck dive at all. Highly recommended!
