Primarily, Mario uses a Vox AC30 tube amplifier. Erick Hansel primarily plays Ibanez RG 321 and RG 421 models. Chon's early work was known to largely shun the use of effects pedals. the band started experimenting heavily with effects pedals when writing Homey. Chon is a progressive math rock band that takes inspiration from a wide variety of sources. While their early music was more metal and shred-based, in the vein of The Fall of Troy and Necrophagist, their sound has changed with new releases. Rock bands such as the Red Hot Chili Peppers & Rush have also played a huge role in influencing Chon's later works of music. Chon have listed pianists such as Hiromi Uehara, Tigran Hamasyan, and Alex Argento as influences in their music. Chon makes extensive use of seventh chords and inversions in their songwriting, and incorporates odd time signatures typical of progressive rock. They also stand out in that they often use major keys, which gives their music an upbeat, peppy tone. Chon's 2017 album Homey saw the band experimenting for the first time with hip-hop and electronic music, most notably on their single Nayhoo.
