Help me out, folks... I recently bought a used Kanstul Custom Piccolo trumpet. (Great horn; great price!) I do miss the pinky ring and after a call to the good folks at Kanstul, they can install one just like on the 1520 model very reasonably. While it's at the factory, I am considering having them install the 4th valve trill crook and 1st valve trigger, also ala the Signature piccolo. What do you people with more experience think? Are the crook and the trigger useful tools to make good music? Or are they "bells and whistles" which only complicate matters? Thanks in advance for the benefit ofvyour wisdom!
