【 Custom options 】

It has been about 15 years since I continued to make metal tongue drums by myself.
I have made around 1500 units.
Taking advantage of that experience, I also support customizing according to customer’s request.

Custom is mainly the type with 6 sounds.
If it is a type with a lot of sound, there will be less parts that can be customized.

If you would like additional options, please add the desired additional options to your cart from the “Product List” on the “Shop Page”.

《 Specific custom content  》

<Color change is free>

Please choose the color from the sample.

The color of the paint is changed irregularly.
It may be possible even if it is not in the sample. Please contact me.

Also, please note that the color development may differ between the image and the actual product.

The painting will be powder coating.

I’m doing my best, but it can also cause some turbulence and pinholes.

Please forgive that there are some aspects that do not look like well-equipped factory products.

〈 Patterning additional 〉cost $ 20

Put a “swirl pattern” and a “marble pattern” on the surface of the instrument.

Compared to a single color, it is more decorative.

After applying the pattern, the pattern is protected with clear paint as a finish.

<Change of scale is free>

There is no problem with changing the specific sound combination or changing the “Key”.

Of course, it is possible to “do not create a scale”, but you can create it yourself by using the attached tuning magnet.

Even if you want to have no scale, I think it is better to create a scale and then change the sound randomly by magnet tuning.

It is also possible to specify the frequency directly.

<Addition of resonance sound> Additional cost 10 ~ 20 $ (per sound)

We will add a resonance sound to the bottom or inside of the instrument.

It costs $ 10 per note to create a resonance at the bottom of the instrument.

Creating a resonance inside an instrument costs $ 20 per sound.

If there is a resonance sound, the sound will fluctuate.

I recommend adding only one or two resonances.

The reason is that if you add resonance to all the sounds, there will be no difference, and the comfort of resonance will not be enhanced.

See the video or blog for more details.

<Change the round shape of the sound board> Additional cost 20 $ (overall)

Change the normal “square sound board” to “round sound board”.

The sound and everything else doesn’t change.
The round sound board also softens the overall impression.


<Installation of output jack> Additional cost 30 $

Equipped with an output jack, such as connecting to a speaker to raise the volume or playing with an effector, the range of performances can be greatly expanded.

The jack is compatible with an average shielded cable with a diameter of 6.3 mm.

Even if you do not install the jack, only the mounting holes are open.



<MANDARA paint>

I am outsourcing to those who are enthusiasts of propanota and have learned design and painting.

Prices range from ¥ 10,000 to ¥ 30,000 depending on the density of the design.

Paint is drawn directly on the surface without a sketch.
To protect the paint, a clear powder coating is applied to the final finish.

It will take from 1 month.
