I have licensed HB6Ys on three of my Lakland Skylines, and I have the US versions on several other basses. Honestly, it's hard to tell the difference. Other than the fact you can't change the orientation on the licensed ones, they set and hold tune just as well as the US ones.
Used these to replace the closed back tuners that came stock on an Ibanez BTB 5 string. The HB6s fit perfectly and are much more stable.
I recently had a tuning head on my SDGR die. Second one on this bass. Second SDGR I know it's happened to. Third Ibanez I know it's happened to. That's four machine heads on Ibby bases that I know of.
Instead of replacing it with another similar part, held in by hopes and dreams, I bought one of these. It fit perfectly and went in like a dream. The post is thicker and the gear is bigger than the other tuners on there. It's a solid part and it looks amazing.
I'll be getting 4 more to replace the other 4 tuners... and it'll cost me as much as replacing it with the original, inferior parts.
I've been using Hipshot products on my basses for many years with excellent results. I have now started using the "LIC" version of the Ultralite bass tuners as well as the original Hipshot USA ultralites. I find the products are made too exacting standards with very high attention to detail and finish. They work extremely well and give years of service. I say "buy with confidence" you will not be disappointed.
