【Since there doesn't seem to be much interest, I will temporarily end this on April 16th.】 Spruce for violin top plate 4/4 Solid spruce. Dried for over 20 years. The grain is about 2 to 2.5mm. The sound quality from tapping is believed to be good. Each part is uniform, has a core, and I feel the balance is good. I think stable characteristics can be obtained by adjusting the thickness of the top plate appropriately. I am selling this because I can no longer make it due to a finger injury. Thank you for looking.
