If I brought a trumpet into you and the ONLY thing(s) you did to it were 1) unstick the frozen MAIN Slide 2) unstick the frozen 3rd Slide and 3) provide me with new corks and felts (I will install the corks and felts myself) Trumpet did NOT receive a "cleaning" service. What would be the "approximate" going rate for such a job? I don't want to seem like I'm whining, but I'm curious if the cost in my head is what shops will charge. I realize that some stuck slides require MORE work then others... if you can't narrow down to a somewhat specific price, then give me a range. The "piece of cake repair" to the "everything short of de-welding it repair" As always, thanks for your time and insights!
