hola tuba comrades,
I have purchased a Willison CC 5/4 tuba (and love every cm of it), and was given Helmet synthetic valve oil. I do not like this valve oil, it doesn't seem to do the job. So I am switching to another brand of oil, but... WHICH ONE?
What do you think is the best valve oil on the market?
