Our Hot Spot, actually designed as a transducer, was used as a drum trigger already in 1984, as one of the very first small size sensitive drum head triggers.
Triggers are also inside drum pads.
Triggers are normally made out of piezo-ceramic material . The carrier consists of piezo-ceramic crystals. These crystals start to vibrate in accordance to the surface they are mounted on and send out equivalent signals. Other than with microphones, you have a wide choice of sounds, and you can get a great variety out of your drumset or pads. You re also independent from room acoustics and it doesn t make a difference if you play big halls or small clubs.
