So easy to install, and effortless to use! Even smoother than I expected: very quick to flip it down and up even for a single note. I also love that all the other strings stay right in tune when the tension changes. And to top it off, its an exact match to the rest of the tuners on my '79 Jazz Bass. Highly recommended!

It work's perfect, tricky to tune and adjust at the beginning but once you get used to it, you do it flawlessly. I installed into a Jaguar Bass MIJ

I installed a full set of HB2’s on my Japanese Fender Geddy Lee Jazz Bass and I liked them so much that I decided to install the BT2 to go with it. Installation was a breeze. It took only a few minutes and now my Jazz Bass goes from standard tune to drop D in one quick flip. I can actually change tuning during a song, and change back and the bass stays in tune the whole time. Now THAT is cool!!!
