Hey, I'm a new member on the forum so I don't really know anybody yet but I was hoping that someone could help me on this. I own a Bach Stradivarius Model 37, serial #482793. I have been experiencing some difficulty with my valves lately and I'm trying to figure out if this was just a bad model year or if there is something wrong with my horn. I had it taken to a repair specialist and he told me that he did not see any dents, bends, or anything that seemed to be wrong. He decided to just clean them as best as he could and see if that worked. They were fine for a couple of weeks and then they started to give me trouble again. They stick very bad and abnormally often (as in a day after I clean them and put valve oil on them!) I'm kinda stuck in a rut here so if anyone has any ideas PLEASE do help me out. Thanks.

Most problems with valves on professional instruments are solved by regular cleaning. The tolerances are much tighter than student instruments which is great for tone production but requires regular cleaning. It doesn't take much gunk in the cylinder to gum them up.

I realize this is an old thread but I thought I would chime in.

You may not need to take the valves out, swab them and then put them back in oiled. I realize this isn't a new instrument judging by the serial number but the best thing for new valves during the break-in is oiling them every time you pull the horn out to play. And I don't mean a little smattering of oil. The two main purposes of oiling are #1 to create an air seal between the valve and casing and #2 to clean the valve, rising any debris off the surface and into the valve caps. Use a good quality, very low viscosity oil such as Clark Viper (my favorite), Al Cass, Blue Juice, etc.
