Huge difference between the basswood used in the high end guitar market and the stuff they use for these.
It's about 60/40 on the end of tonally "alive" to dull sounding cheaper Ibby's I have played. But the basswood used in the Jackson CS and EBMM shop is of a far higher grade.
I never understood this idea that the basswood used by EBMM is somehow magically better. I love my JP7 as much as the next guy, but in no way does it sound significantly better than any of my other basswood guitars with similar pickups. The same goes for the Basswood bodied Suhrs I've had my hands on.
