how long will a bottle of valve oil last him? He keeps telling me he can’t practice because his valves are stuck. He has gone through three big bottles in one year.
well a bottle should last you a year or two, you should only NEED it every few months. Take it to the store you bought it,(Rushes Music, Lunxford, Bandland, etc) unless you bought it on amazon or ebay or some place like that. IF you bought it from amazon, ebay, etc, than those trumpets work for about a month, and then they stop working and you might as well throw them away or jump on top of it because it will be unfixable.
