auccually kench, mahogany is prety bright as tonewoods go. It is warmer than most solidbody woods, but acoustic woods (ie rosewood) are much warmer/bassier
Rosewood has the most bass. If I had an unlimited budget I would build a guitar out of cocobolo. Right now i'm building one with a cocobolo neck but thats just a neck
also KTL, spruce is NOT softer than pine. And the reason it is used in acoustic guitar tops is they need the warmth of a less dense wood as the top matters most in an acoustic. (do you see a acoustic guitar top made out of rosewood or ebony?) My brother has a guitar with mahognay back and red ceder top(now thers a SOFT wood) that ceder has got so many dents it is un belivable, It is unavodiable with ceder. It is just too darn soft.
