It all started when my ni no Ito broke while tuning so I got a new one then it broke the second time I tuned it then broke again and again then now my san no Ito came loose.
Every time I tune my shamisen feels like a horror movie. Maybe I was too rough or rushed
Hi-ho.
If your strings frequently break you may have a rough spot on your koma, bachi, or kamigoma.
You may also be over-tightening or have old strings!
Please inspect your instrument and accessories for any sharp edges - and tell me where things are breaking.
I use to to over- tighten my strings resulting in breaks .
Which section of the string has the break been occuring? That may give some insight into the cause.
