At one time I had a dedicated bed for my snares. Now days, they just sleep on the big bed with me.
but the question remains,
how deep is deep"?
I just got some trusted answers . . .
Generally, a snare bed is about 1/8" deep, and usually covers the distance from one lug to the next. I checked an Acorolite, which is 8 lugs. This seems to bear out the statement. It is about the distance of one lug span, and about 1/8" at its steepest point. The 1/8" is about 3" to 3.5" long before it tapers out.
