It seemed the best course of action was to get some feedback from those of you with more experience in this area before contacting the people at Harrelson. I'm a first year trumpet player, so a bit of caution is in order whenever anything is undertaken.
They (Paul - Harrelson Trumpets) have ALWAYS been a pleasure to work with! And the quality of their kits is nothing less than world class. It was certainly worth the wait!
