Solemn Tones is a Belgian music software company founded by Maxime De Cock, specializing in virtual instruments, amp simulations, and effects plugins designed for rock and metal production. The company is best known for its flagship Odin line of virtual guitar instruments — the latest being Odin III — which was sampled using an ESP LTD SC-608 eight-string guitar equipped with Fishman Fluence pickups and an Evertune bridge, offering tuning ranges down to double drop C. The Odin is a MIDI-based instrument that can be loaded directly into a DAW without requiring Kontakt, and includes features like multiple palm mute types, auto chord delay, force vibrato, and auto slide for realistic playability.

Beyond virtual guitars, Solemn Tones offers a range of instruments and tools under a Norse mythology–inspired naming scheme: Ragnar Drums and Mjölnir Drums for drum production, Loki Bass 2, Sanguine Bass, Kraken Hybrid Bass, and MayoBass for bass, and the Fenrir amp simulator. The company also produces the Artifact Suite, a collection of effects plugins including BEAST, SMASH, FROSTBITE, ROOM, and OVERLOAD, as well as cinematic sample packs under the Bifrost name.

Solemn Tones has built a following in the heavy music production community, with artists and producers from bands such as Ice Nine Kills, Epica, Rings of Saturn, The Amity Affliction, and Butcher Babies among its users. Producer and guitarist Jason Richardson and content creator Nik Nocturnal are also noted users of the brand's plugins.

Solemn Tones has 2 products cataloged on Equipboard, including Kontakt Instrument and Virtual Instrument. Their gear is featured by 2 artists, with the strongest followings in Electronic, Orchestra, and Classical. Notable users include The Midnight and Derpcat.
