Now you may larf if yer like, but when i when on hols to germany i mysteriously found myself in thomanns music shop near Bamberg somewhere. Any road up after testing a goodly number of altos i bought a system 54. Sounds great to me, looks good, and handles well to me again. But you do have the problem of getting a bit of water, saliva, snot (no other bodily liquids that i'm aware of) on the brass and a little green oxidization mark appearing just where its nearly impossible to get at. Do folk oil the brass a bit to prevent this? How do you get it off without taking the tarnish effect with it? Any suggestions other than selling it (particularly to you) might be entertained. Thanks for your input.
