Conn-Selmer 1877 BACH STRAD MAIN KIT
Maintenance Kit are many spare parts that will eventually need replacing on any trumpet. The valve springs and guides will eventually wear down over time causing the valves to either spin inside the casing or not return correctly.
These parts become essential. As well as this, parts that can often get misplaced or broken are included in this kit. The 3rd valve rod and nuts are often things that can be misplaced making them a great asset to this pack.
