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.

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.

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.
 

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!

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 : 

In November 2017 MRO saxophones overhauled two popular Buffet Crampon clarinets at the same time. That was also a great opportunity to finally determine exactly what the actual differences are between these two types. The RC is considered the entry-level professional model; the E13 as an Intermediate model. Because I overhauled both types before, I already thought that the differences were minimal, especially with the older models.

Here is the list of the different Selmer mouthpieces for clarinet and saxophone, with their associated markings.
