The Pampet TruTra is an excellent way for trumpet players to warm up, as it allows the player to blow hot air through a simulated lead pipe. It certainly is easier than removing your trumpet's lead pipe and replacing it when you're done. You can simulate playing low, high, loud or soft and even play around with the valves. In addition, the TruTra is small and light enough to pack in a suitcase or backpack. Despite its light weight, the TruTra is sturdy and seems unbreakable. For about $30 (U.S.) it's a terrific value.
