Your sound volume is normal!
You can hardly hear the sound because the fiddle was so made– it is meant to be “Silent”. (You are lucky because you don’t hear my poor execution)
Although instrument is unplugged, the stethoscope’s earpieces are plugged into my ear holes, giving me a pain and distraction while playing… (It’s a good excuse for my terrible performance)

Until now, I have made several “fake musical instruments” most of which were electric. I call them fake because there aren’t such things like “Electric Solid-Body Morin Khuur”, “Silent Electric Evenki Shaman Drum”… One day, a musician asked me to make a pochette fiddle, which was supposed to be a serious project. I managed to finish it and consequently had an additional orders by the other musicians.
Then I asked myself “hey! Can you really make those “real” musical instruments without being able to play them?” and also thought “if only I had one, I would be playing it… Yeah, I must make one for myself”.
My first fiddle had a laminated carbon FRP body and a gourd to enhance low sound, and of course electric pickup for plug-in play.
As you know, the screeching noise made by a violin novice is intolerable to bystanders but the player must listen to it… My first fiddle had a resonance body, so that it is impossible to get rid of the sound. Then I had to make another one without sound amplifying structure yet can supply ample sound to the player.
Stethoscope is the solution. The fiddle without body produces very soft sound that cannot annoy neighbors even in the middle of night. Along with bone conduction, the stethoscope conveys sound loud enough for the player. Also, good thing about it is that you don’t have to deal with electric stuff such as shield line, amp and headphone/speaker. Well, there is always a drawback when you make something new… Stethoscope is not meant to be worn for long time, and gives you a pain in your ear holes if you keep using it even for few minutes.
When I began practicing to play the violin, I couldn’t hold it under the chin, so I had to invent a “violin strap” something similar to a guitar strap. The strap turned out very useful– for a short period of time. As I get used to playing the instrument, the contraption has become a nuisance every time I wear it.
My dream is to play J.S. Bach’s Suites for Unaccompanied Cello, which was not for violin– but anyway, my fiddle is a fake instrument and I myself am a fake player without a formal training of violin at all, so who cares!
