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. Bravo, Hipshot

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.
