Therevox began making instruments in 2004. The ET-5 is inspired by the Ondes Martenot, so the tradition goes way back. The ET-5 has been in development now for two years.
New features with the ET-5 include a patch panel, an FX loop with a place to put and power guitar pedals (on the right in the above photo), pressure sensor on the fingerboard, with improved ringed action on a longer fingerboard. There is also improvements made to the internal spring reverb, and many more new additions.
(The above photo is an earlier ET-5, the front panel is more of a khaki color as shown below, or in the video.)
I like that the controls are so distinctly presented on the top panel. From the video i get the feeling that this synth has a real presence and unmistakable character. It sounds great.
This video gives a demonstration of 10 of the sounds possible from the ET-5, one sound shown a minute:
No price announced yet but it will likely be in the mid 2000 Euro/USD sort of range (my guess based on the last ET-4 price). You can get in line for delivery later this year with a deposit.
