Neon Egg is a UK-based boutique effects pedal builder best known for the Planetarium, a creative multi-effect pedal housed in an enclosure styled after vintage analog synthesizers. The Planetarium chains a stereo modulated reverb into a stereo-modulated echo and then into a compressor with an external sidechain input, with the signal path intentionally non-reroutable to encourage lush, tempo-synced ambient textures.

The Planetarium has gone through several revisions — V1, V2, and V3 — each expanding on the combination of reverb, chorus, delay, and dynamics processing. Its oversized control-panel layout, with rows of knobs and toggles, has made it a favorite among ambient, post-rock, and electronic musicians who often treat it as a desktop unit as much as a pedalboard fixture.

Sold primarily through Neon Egg's own webstore and a small network of boutique retailers, the brand has built a cult following in the pedal community and among synth-focused players looking for guitar-pedal-format sound design tools.

Neon Egg has 3 products cataloged on Equipboard, including Multi Effects Pedals. Their gear is featured by 3 artists, with the strongest followings in Rock, Electronic, and Pop. Notable users include Tim Pierce, Quinn Whalley, and Ryan Petersen.
