Here you will find my personal reviews of instruments that have been repaired or overhauled at MRO saxophones, and of which little or no information is available on the Internet.

On customer request MRO saxophones performed a modification to the LH pinky plateau of a Buescher 400 baritone saxophone. The modification wias performed because the LH plateau of these saxophones is quite heavy to operate.

MRO Saxophones carries out revisions to both modern and vintage instruments. That is one of our core tasks.
Here you can find some examples of these revisions.

This week MRO saxophones received a Yamaha YTS-62 purple logo for repair. That was a great opportunity to determine the differences between the YTS-62 and the YTS-32. A lot of information can be found on the various internet forums, and it is even claimed that the YTS-32 is a 'stripped-down' version of the YTS-62. Is this true? ...... Time to put both saxes on the workbench and inspect them accurately!

This original warranty card from 1927 was hidden in the case of an alto saxophone Conn New Wonder II (ChuBerry). These warranty cards are rare and most have disappeared over time. It is in very good condition and contains valuable information on instrument maintenance in the nine pages of the booklet; a must for every Conn enthusiast. I have scanned all pages: see attachment.
 

MRO Saxophones performed a series of Buffet Crampon clarinet overhauls and maintenance checks early 2022, including two S1 models. The S1 is a rather uncommon version and not that many were made during the 1970´s. The first one is an early one from 1974, and the second one is a late one from 1980. I notices some important differences between these S1 clarinets, and couldn´t find any info online on these differences. Both clarinets have the ´F´-prefix and were made for the European market.

The Yanagisawa A4 alto saxophone is considered Yanagisawa's first semi-professional instrument. They were built from 1966 to the mid-1970s. There is not too much information online about these saxes, but I have collected this and supplemented it with my own observations.

Undoubtedly 1 of the most sought-after vintage alto saxophones is the Conn Transitional. These were built in many versions between 1930 and 1936. Much info can be found on Matt Stoher's website, however that info is not complete. 

Selmer serie 9 versus serie 9* clarinet :

Both the Selmer serie 9 and serie 9* are professional clarinets for the advanced player. They are not the same but there seems to be lots of confusion and incorrect info on these models.......

Here's some interesting stories about the Selmer serie 9 and Serie 9* clarinet I found on the internet :
