How do i make resonate my shamisen?

so i was playing the instrument while recording to see my performance and the sound didn’t resonate that much
somebody know what could be the problem?

Hi there, welcome.

Can you tell me more about your situation and what you mean by resonate?

Is the sustain really weak?
Is there no sawari?
Did you notice this in the recording or when playing?

so the sound feel very week almost like a toy
also is synthetic skin and it has a little hole on top so i kinda think that is the problem
and i have not activated the sawari also i notice this while recording and playing
thanks for the help!
