I picked up a Tama Artwood snare about 20 years ago. Really nice finish, 10 lugs, 5.5 x 14. Its well made and has a great throw off. After I picked it up I got in to the Roland V drum and did not touch it. A few days ago I decided to put it on the acoustic kit and freshened both heads. To my surprise there is no snare bed on the bottom bearing edge. Is this a fault? I can see the bottom head sitting better with out it, and the snare sounds great. But I was expecting to see a cutout. Is this common? Thanks.
