As a guitar builder I might have installed all types of guitar tuners on my or my customers‘ guitars. I love the way these ones work and the freedom of placement they offer. Basically, you can arrange them in any order you like and not just in the traditional 6 in line, or 3+3. Moreover, the 40:1 ratio is extremely precise and they keep the tuning regardless of how much you bend the strings. Also, they are locking tuners by design. All in all, they are an excellent choice for anyone who is willing to try something less traditional. I highly recommend them!
