This is a custom daCarbo trumpet made for a client of Stephan Maier Music upon Stephan's askance. It passed through our office last year and we got photos.
Swiss daCarbo trumpets are simply top of the guild quality and are played worldwide. The projection and easy slotting is legendary. The daCarbo trumpet line is primarily two models:
This Unica+ features the large Maier bell flare without the carbon bell branch, and Saturn water keys. The finish is satin gold lacquer, but your choice is available. It was a hit with the players here. They'll build you another if you like. 30-60 days, likely less.
The photos with two trumpets show size comparison between the standard Unica and the Unica+ bells.
