I believe that every time we bring our instruments to the shop to get repaired, we need to be specific to the technicians as far as what we want done. Any upgrades or special parts, if you want more actions to the keys, have pads cleaned or replaced, we need to let them know. Not all shops will automatically do this for you unless you are specific.
Now, some shops will do an evaluation on your horn and make some reccomendations to be done, you dont have to accept and they should tell you first and get your permission before the job is done. But, its highly reccomended, depending on the testimony and background of that shop; that you accept their reccomendations. Must of them know what needs to be done in order for you to have a quality instrument in your hands.
Its important to keep this in mind, this will help you make good desicions for a better outcome. I recently had my Flenz tenor sax repaired, they did a fine job done on the horn, however; i made the mistake of not telling him that some pads needed to be replaced, he didnt replace them. They still have some life to them, but i would have avoided taken it to the shop again in the near future.
Take your time at the shop and get it done right.
