    Comments about Boss TU-01 Chromatic Tuner:

    All of my acoustics have built-in tuners, and so I've never needed a clip-on tuner. Until now! I recently bought an acoustic which does not have a tuner, so I needed a solution. I borrowed a couple different brands from friends but they didn't perform well - accurate but a 'slow' response time. On a whim (and faith in Boss products) I bought this Boss tuner and I am very impressed! It responds quickly when I pluck a string, the display is very clear, and it is more compact than the photo suggests (which is a good thing). In 30 years of performing and buying gear, Boss has never let me down. The streak continues :)

        Comments about Boss TU-01 Chromatic Tuner:

        I bought two of these at the same time. I was going on a tour overseas and wanted to make certain I had a backup in case one failed. Well, it turns out BOTH of these failed- the exact same way. The piece that is between the tuner and the clip either broke or came unlatched at the tuner section . I've yet to figure out what's wrong. The tuner section just dangles there. I kept them in the SKB flight case with my G&L ASAT. They were in a place where they didn't get bounced around so I rule out poor handling. I bought these because they were Boss products. Everything I've owned from Boss has been rock solid. Really disappointed in the build quality of these.

        I hate giving bad reviews but these are poorly made.


        Works great for mandolin.

        I just started using my TU-01. I'm using it for mandolins and mandola and it works very well.
