As the music director for an a cappella group, I use my pitch pipe every day. Most pitch pipes break after only a month if not a few weeks of intense use – they are poorly made and rendered unusable if only one of the twelve pitches does not work. This was changed by the Tombo P-13E Pitch Pipe.
Made by the Japanese harmonica company, Tombo – founded in 1917 – the P-13E is a new take on the classic pitch pipe design, with a plastic body (instead of the usual metal) for a more durable exterior and protruding mouthpieces on every note instead of a single, rotating mouthpiece.
