Moen is a Hong Kong-based manufacturer of compact guitar effects pedals and signal-routing accessories. The company designs and builds its stompboxes in-house, and its catalog spans overdrive, distortion, modulation, delay, looper, and utility pedals sold through dealers like Reverb, Guitar Center, and Musician's Friend.

The brand is perhaps best known for its small-enclosure modulation and dirt pedals, such as the MO-VB2 Shaky Jimi vibrato/chorus, the MO-VM Violent Metal distortion, the AM-CH Analog Chorus, and the Buffalo speaker simulator with DI. Alongside its effects line, Moen produces switching and routing gear aimed at players who run larger pedalboards, including the GEC series of MIDI-capable effects loop controllers (GEC8, GEC9) and the AB BAR true-bypass loop switcher.

Moen's pedals occupy a budget-to-mid-tier price point, and the brand has built a niche reputation among hobbyists and working players looking for affordable takes on classic effect types. Its loop switchers, in particular, are frequently cited in pedalboard-building discussions as a lower-cost alternative to more expensive routing systems.

Moen has 41 products cataloged on Equipboard, including Switch Effects Pedals, Multi Effects Pedals, and Compressor Effects Pedals. Their gear is featured by 7 artists, with the strongest followings in Rock, Latin, and Pop. Notable users include Luke Boerdam, Jeremy DePoyster, and Luke Parish. Most Moen products sit on the budget-friendly end of the spectrum.
