Sterling Virtuoso Main Tuning Slide Trigger Sticking
I am growing increasingly frustrated at my tuning slide trigger mechanism. I have a relatively new Sterling Virtuoso Custom, and this sticking is driving me crazy. It doesn't gum up every time I use it, but it has at the worst times. There's no way this horn should already be having issues. I can confirm that there has been no damage to the horn. I currently use Denis Wick Ultra Pure Linkage and Lever Key Oil. Am I missing something with the screws on the assembly? Thanks for the help!
