Customer ratings for lefreQue Tutorial 33mm

I thought I couldn't go wrong for €21. And then the surprise, the low C comes easily and securely, in the high register the notes are suddenly reasonable and the vibrato runs like clockwork. I am totally thrilled.
Now the question arises, are the metal parts even better?
Highly recommended

Although I was a bit skeptical at first, I have to say that this tutorial really improves the sound of the instrument. There are two different sizes for the alto saxophone. I chose the smaller tutorial 33mm, because this also fits on my other instruments. However, for the alto saxophone, the larger Tutorial is more recommended (I think these are 41mm), at least if you don't push the mouthpiece all the way for tuning reasons. But it also goes with the tutorial 33mm. Otherwise, it is really super.

I had the opportunity to review, very positively, this product for having purchased several, on several occasions, for my flutes. I return once again to reiterate the usefulness and excellent value for money, although I seem a bit excessive shipping costs (Euro 9.90).

Have the part tested yesterday the first time in use and expect again I'm totally thrilled, especially in the piano you notice a much better response of the clarinet. I will test a bit further and will then probably get me the higher-quality sound bridge.

have been using the sound bridges for a while, this one serves as an upgrade over a pure brass bridge on my Brancher soprano, the material improves the sound some more.........

bought for the trumpet, but is not permanently or permanently used, only for some pieces of music ; tone is a little easier to produce and sounds a little different than without, but is not so that previously oblique tones are now full and clear ;)

I would not have expected the difference in sound, and would recommend it to others.

If I have to be honest, I was not convinced about what was said about the effectiveness of the LefreQue system. So, a bit hesitant, I decided to buy two, the less expensive ones: one for the C flute and the other for the G flute. Instead, I must admit that the LefreQue really works! It makes it easier for me to emit the sound and the sound itself is rounder, softer and with a higher volume and projection in the low tones and I can't tell you about the mid and high ones. A really good product that delivers on the promises for which it was designed and released for sale! The 33mm has arrived and as I told you it works great on my C flute, now I'm waiting for the 41mm and I want to see how it works on my alto flute, although I think for the latter I will have to buy at least another one as I use the curved head. In any case, by now I'm sure that for this other flute the LefreQue will work just as well as the first one, so I can't wait for it to arrive.
The only negative thing I have to say is that the shipping cost is a bit high!
This is my experience with this product!

Sincerely
