Radel Electronics is a Bangalore-based manufacturer of digital versions of traditional Indian musical instruments. The company traces its origins to 1979, when engineer-flautist G. Raj Narayan invented the electronic tanpura and demonstrated it at the Music Academy in Chennai; Radel Electronics Pvt. Ltd. was formally established in 1994 and operates out of Electronics City in Bengaluru.

The brand is best known for its digital tanpuras (the Saarang line, including models such as the Saarang Maestro and Saarang Sparshini), digital tablas and combined tabla-tanpura units like the Milan+, and digital harmoniums under the Maadhurium name. Other product families include the Dhruva sruti box, the Sunadavinodini electronic veena, and digital lehras, srutipetis, and swarmandals — instruments aimed at Hindustani and Carnatic musicians who want a portable, tunable replacement for an acoustic accompanist.

Radel positions itself as a pioneer of electronic Indian instruments and sells through its own site as well as Indian and international retailers (Amazon, IndiaMART, regional music shops). Its instruments are widely used by classical Indian vocalists and instrumentalists for practice and performance accompaniment, where consistent pitch and tala reference are required.

Radel has 2 products cataloged on Equipboard, including Controllers and Tabletop Synthesizers. Their gear is featured by 1 artist, with the strongest followings in Rock. Notable users include Eric Cannata.
