Customer reviews
What customers say
Summarized and selected by AI from recent customer reviews
This tuner excels with multiple temperaments for baroque music (415Hz, 392Hz) and offers easy reading. Customers praised its precision for tuning guitars, violins, cellos, and even pianos. However, some noted the plastic casing feels low quality, English notation may not suit French customers, and the sound mode volume lacks control.

I've been using it almost every day for two years, I tune with guitars, violin, cello, and it's even accurate enough for me to have been able to tune my piano with it (and several pianists have played after me, it's well tuned).
Default: the sound it emits in “sound” mode is quite horrible, and its volume is not adjustable enough, it is often too loud.Automatically translated

Essential tuner for baroque music, 415, 392 with several temperament options. I had the old version that followed me for about twenty years, so a good investment. The plastic on the case and buttons seems to be of low or even mediocre quality, which is a shame.

I am very satisfied with this first order received in 48 hours (instead of the expected 5 days). The metronome is great and the packaging was very careful for shipping. The price is very reasonable. For sure, I would recommend Woodbrass.
