For advertisements, see the maker's real name: La Monte. Martin Frères clarinets was a maker, extending at least to the early 1800's. So they must have been bought out at some point by La Monte.There were wooden models as well as the Grenatex. And there was a professional model Martin Freres as well, the Deluxe.The model reviewed on this page was designed as an inexpensive student instrument.Serial # E 1751 For Fernando in Berlin.Barrel: 64.1mmBore LH joint top: 14.6mmBore LH joint at bottom: 14.4mmIntonation results taken when playing loud and not lipping. See how to interpret these results on the Model Comparison Page.
There are images of ads for the wooden Martin Freres on the Grenatex page.
For this test, I pulled 0 at the barrel and almost 1mm in the center.
Intonation summary: This needs some undercutting on the throat tone F, A and Bb holes. Many players do not play as flat as me, and this test was playing loud. So the flatness of -4 or less will not be a problem for many players. Higher numbers in the throat tones are the results of undercutting.
Key work quality: The key work is a bit softer than I would like, but quite thick. It will stay in adjustment with reasonable care. The rings have a sharpish edge visible in the pictures. This makes the clarinet not feel comfortable to me, but someone playing it regularly would not notice this.
This clarinet is most appropriate for: An adult returning to playing the clarinet. Or a beginning student on a budget.
