good product

Bought for a Bb Tuba, not practical at all, impossible to fix it on the mouthpiece branch, while the manual recommended fixing it there ?? Also, the clip doesn't seem effective enough... probably good for other instruments but not for a tuba!

Very responsive and very precise tuning. However, be careful because it does not offer transposition! Indeed, when playing with a saxophone, the note we play will be indicated in its true sound (in C), for example the "G" on the alto saxophone will be seen as a "Bb" by the tuner.

Fits my instrument very well. Now I just have to understand how it works.
