The company focuses on continuous-pitch instruments and is known for building a modern [analog synthesizer](/source/Analog_synthesizer) inspired by the rare [Ondes Martenot](/source/Ondes_Martenot).[1] First commissioned in 2004 to build modern version of the [Electro-Theremin](/source/Electro-Theremin) as used by [The Beach Boys](/source/The_Beach_Boys) on their 1966 single "[Good Vibrations](/source/Good_Vibrations)", only 12 of these instruments went to musicians and studios in North America and Europe.[2] In 2010, Therevox was commissioned by [Montreal](/source/Montreal)'s [Breakglass Studio](/source/Breakglass_Studio)[3] to build a new instrument and designer Mike Beauchamp combined the Ondes Martenot's *au ruban* and *touche d’intensité* interface with a dual oscillator analog synthesizer similar to the [MiniMoog](/source/MiniMoog).[4] The design included a built-in [spring reverb](/source/Spring_reverb) and this prototype became the ET-4 [5] model that has been available since 2012. The last ET-4 ever produced was acquired by Canada's [National Music Centre](/source/National_Music_Centre) in 2019 under the condition that the instrument continues to be made available to musicians. The instrument is currently housed in Live Room B in StudioBell and is a part of the National Music Centre's "Living Collection".[6] According to the online marketplace [Reverb.com](/source/Reverb.com),[7] the ET-4 was one of the most watched synthesizers of 2023. In March 2021, the Therevox ET-5 was announced and began shipping to advance customers shortly afterwards.[8] There is currently a two year waiting list for a new Therevox ET-5.[9] ## Notable users of Therevox instruments - [Anton Sanko](/source/Anton_Sanko)[10] - [The Besnard Lakes](/source/The_Besnard_Lakes) - [Belle & Sebastian](/source/Belle_%26_Sebastian) - [Beth Gibbons](/source/Beth_Gibbons)[11] - [Billy Jay Stein](/source/Billy_Jay_Stein) - [Brad Mehldau](/source/Brad_Mehldau) - [Brian Marsella](/source/Brian_Marsella)[12] - [Chelsea Wolfe](/source/Chelsea_Wolfe) - [The Decemberists](/source/The_Decemberists) - [Floating Points](/source/Floating_Points)[13] - [The Gertrudes](/source/The_Gertrudes) - [Gil Assayas](/source/Gil_Assayas) - [Iron & Wine](/source/Iron_%26_Wine) - [Jason Isbell and The 400 Unit](/source/Jason_Isbell_and_The_400_Unit) - [Jean-Michel Blais](/source/Jean-Michel_Blais) - [Joan Shelley](/source/Joan_Shelley) (played by [Jeff Tweedy](/source/Jeff_Tweedy)) - [Jon Batiste](/source/Jon_Batiste) (in [American Symphony (film)](/source/American_Symphony_(film)))[14] - [Klô Pelgag](/source/Kl%C3%B4_Pelgag) - [OneRepublic](/source/OneRepublic) - [Pearl Jam](/source/Pearl_Jam) (2024 Dark Matter World Tour, played by [Josh Klinghoffer](/source/Josh_Klinghoffer)) - [Sharon Van Etten](/source/Sharon_Van_Etten) - [Suuns](/source/Suuns) - [Team Me](/source/Team_Me) - [The Veils](/source/The_Veils) - [Wintersleep](/source/Wintersleep) - [Yann Tiersen](/source/Yann_Tiersen) The ET-4 and ET-5 have also been used on soundtracks for [Planet Earth III](/source/Planet_Earth_III), [Hulu](/source/Hulu)'s [The Handmaid's Tale (TV series)](/source/The_Handmaid's_Tale_(TV_series)), [The Walking Dead: Dead City](/source/The_Walking_Dead:_Dead_City),[15] [Halo Infinite](/source/Halo_Infinite),[16] [Bad Banks](/source/Bad_Banks), [The Inventor: Out for Blood in Silicon Valley](/source/The_Inventor:_Out_for_Blood_in_Silicon_Valley) and [horror film](/source/Horror_film) *[Nurse 3D](/source/Nurse_3D)* starring [Paz de la Huerta](/source/Paz_de_la_Huerta) and the [Salvatore Ferragamo](/source/Salvatore_Ferragamo) inspired "White Shoe".[4] ## See also - [Ondes Martenot](/source/Ondes_Martenot) ## References 1.
