Tuning a Moog Etherwave standard & plus theremin - by Maurizio Vento 

Thank you very much, this video saved my life ❤ I have a concert after tomorrow with the theremin and I thought it was not going to be fixed but thanks to your video only it was possible. Grazie mille

Great video. My EW Standard's pitch has gone screwy. Knob at 12 o'clock and pitch descends as i move towards antenna. I contacted moog and they advised against calibration as long as I was able to achieve a playable range🙄

First, listen to see if the pitch goes higher or lower as you draw your hand away from the pitch antenna. If it goes higher, adjust L5 so that the pitch descends through the zero point and then starts rising again; now it should be in the right direction. The next step is to grasp the pitch antenna and adjust L5 so that the frequency you hear is in the neighborhood of 3.8 kHz. L5 and L6 interact, so there will be a decent amount of back-and-forth between the two adjustments. Once you have the top end around 3.8 kHz, move your hand away and see where the zero point is located. It will likely be too close (too short a scale range); to adjust, stand at arm's length from the pitch antenna and reach over from the left to adjust L6. You want to adjust it so that the zero point is about an arm's length from the pitch antenna. Generally this involves turning the lug in L6 in the same direction as you adjusted L5 to get the top end. The first time you do this, it will probably drive the top end higher than you wanted it to be, so go back to grasping the pitch antenna and turn L5 in the appropriate direction to get back in the neighborhood of 3.8kHz. Notice which direction it went (higher or lower) as a result of setting L6; and overshoot in the appropriate (opposite) direction to cut down on the number of times you have to go back and forth between the two adjustments.

I used this video once again, and thank you again.

Thank you very much for this saved my life. Much more useful than the manual!! Molto grazzi

Thanx!

Ciao quindi agendo su l6 aumenta il range del campo ? Perché sto notando dopo molto tempo che lo uso , guardando vari filmati che quelli molto bravi hanno un range di movimento più ampio del mio , faccio melodie semplici ma mi devo muovere in un range di movimento più piccolo ( più difficile )

Good video, helped me with tuning a EW I bought second hand which was badly out of tune. You could add more detail on the last step, by explaining what effect it will have to bend the wire close vs far away from the aluminum panel

Salve Maurizio, sono molto interessato all'acquisto di un theremin a breve ho visto che per migliorare la linearità del campo e la risposta ai bassi bisognerebbe mettere l ESPE01, questo discorso risale al 2014. Mi domando se nel frattempo in fabbrica non hanno effettuato questo upgrade. Così comprandolo ora non sia superflua tale modifica

Grazie mille! This video helped me a lot.

This is very helpful. I just tweaked L6 my Etherwave so my pitch knob was back in a useful range. Thank you very much.

Hi Maurizio, even though this is a great explanation, I am terrified of doing something wrong if I start tweaking the insides of my Etherwave. I bought a second hand one yesterday, and although it appears in great shape, there's no sound coming out of it. Do you know anyone in London who could help figure out what's going on? I would like to avoid sending it to Thierry by mail..

Mille grazie.

Thanks from me also, this was really helpful

Thanks! This is very helpfull.

Maurizio, many thanks! One cavil . . . the Moog manual says to remove "the temporary shorting connection across C28" before adjusting the C11 volume slug. You don't mention this. I tried your method, without ever touching C28, and it seemed to work fine, as you describe. Explanation?

great video, and only video!! thank you I want to ask you about an issue I get with my theremin! It changes its tunning to a smaller range alone on its own!! is this a problem? or i should tune it again form inside like the video?

OKay I have to tune it with Metal allen key! cant find the plastic one at all!! is it that dangerous to do it?
