What is the difference between solid spruce soundboards and laminated soundboards?
The fact is that this statement is a bit of a misnomer. It is truly a question of which way the spruce wood is laminated. Spruce is selected as soundboard material because of its resonant qualities. Some manufacturers use spruce planks which they glue edge to edge or horizontal lamination. Other manufacturers use what we have come to call plywood or vertically laminated spruce. A test was run many years ago of the two laminated spruce versions and no significant difference in resonance was detected.
