Only with accoustic guitars :lol:
That's about as far as my experience of Spruce stretches to too! :lol:
Here's some info I found on spruce as a body wood:
Spruce:
Very soft to the touch, it is extremely stiff for it’s overall density. Like Alder, it’s another wood with a hard skeleton and soft meat. So in a solid body, it will produce tremendous resonant, open midrange, while retaining high frequency attack, and having good low end breath. Because of the low density overall the sound wouldn’t be perceived as having less midrange than Basswood. The mids will be just as powerful and dynamic amidst the addition of clear highs and lows. Probably the most full frequency body material accepted.
Production notes: Rarely used because its softness requires a heavy finish, or a composite “shell” like the Parkers. The Parker isn’t the best representation of the sound of a Spruce body since there are many other unique construction methods and synthetics used in the Parker. Would work well with veneer caps or a top, and would offset some of the compressed sound you get with neck through construction.
