Tonight, we have on the bench a somewhat rare beast, the contra-alto clarinet (also referred to as the EEb contrabass).
This one has probably only ever had minimal servicing during its life. There’s some serious wear in the rods, the LH F#/C# lever post has been snapped off, and plenty of tarnish.
This is getting overhauled with Musicmedic Roopads (besides being lovely pads, I love the white colour!).
Here it is, being disassembled (you can see the old pads), in the bath, and the upper section, with pads installed.
