Subkick is a type of electronic drum trigger designed to capture the sound of a kick drum without the need for a traditional microphone. It typically consists of a pad that is placed in front of or attached to the kick drum, converting the vibrations from the drum into a MIDI signal or audio output. This allows for greater control over the sound and volume, making it popular in live performances and studio recordings. Subkick is often used in conjunction with other drum triggers or microphones for a more versatile sound.
