What is the difference in sound between spruce and cedar?
Classical guitars with cedar soundboards tend to have a very open sound and play in quickly. The tonal color of cedar affects the entire tonal palette of the instrument. I think of it as being similar to the way a colored lens filter tints an entire photograph. Classical guitars with soundboards of spruce tend to be more transparent, have more clarity, and yield a broader range of tonal variation. Guitars of spruce and cedar can be built to sound brighter or darker, regardless of the type of wood used.
