Electronic drum sets were first introduced in the 1970s and 1980s as drum machines like the Roland TR-808. These early drum machines let drummers replicate drum sounds electronically using analog synthesis. However, the sounds were primitive compared to acoustic drums.

In the 1980s and 1990s, electronic drum sets began using digital samples of acoustic drums rather than synthesized sounds. This allowed electronic drums to sound much closer to real acoustic drums. Electronic drum sets consist of three main components:

Drum pads and triggers – These are rubber pads or mesh heads that the drummer strikes, similar to acoustic drums. The pads have sensors that detect the hit, velocity, and location.

Sound module – The module contains prerecorded digitized sounds of drums that can be assigned to each pad. The drummer can customize and tweak the sound of each pad.

Amplification system – This amplifies the electronic drum sounds so they can be heard. Electronic drums usually output to headphones or a PA system rather than acoustic projection.

Some benefits of electronic drums include:
Volume control – Electronic drums can be played silently with headphones for practice.

Customizable sounds – Drummers can replicate the sound of any type of drum.

Cost – Midrange models are more affordable than professional acoustic kits.

Smaller size/portability – E-drums take up less space and are easier to transport.
