In some styles of music, drummers use electronic effects on drums, such as individual noise gates that mute the attached microphone when the signal is below a threshold volume. This allows the sound engineer to use a higher overall volume for the drum kit by reducing the number of "active" mics which could produce unwanted feedback at any one time. When a drum kit is entirely miked and amplified through the sound reinforcement system, the drummer or the sound engineer can add other electronic effects to the drum sound, such as reverb or digital delay.
Optical pickups are another type of non-magnetic pickup. They use an infrared LED to optically track the movement of the string, similar to the mechanism of modern computer mice, which allows them to reproduce low-frequency tones at high volumes without the "hum" or excessive resonance associated with conventional magnetic pickups. Since optical pickups do not pick up high frequencies or percussive sounds well, they are commonly paired with piezoelectric pickups to fill in the missing frequencies. LightWave Systems builds basses with optical pickups.
At the heart of most stages is the acoustic drum set. It's made up of tom-toms, snares, at least one bass drum and an array of cymbals. You'll find all of those here, and there are choices for anyone. If you're just getting started as a drummer, you can get up and running fast with a shell pack or drum kit that gives you everything at once. Or, if you prefer, you can pick individual pieces ""a la carte"" to customize your own set from the ground up. The choice is yours.
