Hi there. im 18 and found out about this instrument about a year ago, and it interrest me alot. I have been playing Euphonium for 7 years, and started with keyboard here a while ago. Im planning to buy a Moog Etherwave Standard as they sell them here in Norway, but the problem is that they dont sell Theremin Amplifiers here, and to import that will be very expencive, therefor i wonder. Can an ordinary 15 watt guitar amplifier work? And what extra equipment is there to buy?

Hi Jan, welcome to Theremin World.

Ideally you want a keyboard amplifier - one that can take line-level output as from a keyboard and that responds well throughout the audio spectrum.

The line-level output of the etherwave is a lot more powerful than guitar levels and can cause unwanted distortion of the sound if played loud on a guitar amp.

There is a simple modification to the instrument - replacing one resistor (page 9 of the hot-rod manual, download here ( - which lowers the level to work with a guitar amp.

Or you can buy a cheap low impedance inline volume pedal and use that to attenuate the signal.

It is more expensive than a resistor, but has the advantage that it is easily removed to use a different amplifier, and I have found that some effects pedals - particularly my reverb pedal - work better put in the effects chain before the volume pedal has reduced the volume.

The disadvantage is that occasionally I step on mine inadvertently and am startled by the sudden increase in volume. I also suspect that these incidents are not good for the amplifier. My poor little Fender 15R guitar amp seems more hissy than it used to be, and I think this might be the cause.

You will need a microphone stand to support your etherwave and an audio cable to connect the theremin to the amplifier.

I suggest you either use an amp with built in reverb or buy a reverb pedal as the theremin's tone can be very dry without a little bit of reverb.

I think the best route is to use an inexpensive amplifier until your playing skills develop, and then audition amplifiers at a music shop and choose one that has a sound you like.
