I bought a used trombone but the slide was hanging so I had it repaired (slide reconditioned). The slide moves freely now but is a little noisy (shh, shh) and feels the slightest bit gritty at portions. This is my first trombone. Is this normal? Freshly oiled, still happens. Obviously I can still practice with it, but I'm wondering if the repair job went as should be expected or if I ought to be worried about doing damage to the slide by using it like this. Thanks for any help.
