Bottom line is you never *really* know what youre gonna get. Its just educated guesses based on aggregated experience of the user group here on the behaviour of certain pickups in certain woods, and how they combine with wood species archetypal sounds. Two pieces of wood from the same tree can sound very different, and with plywood and the various cheap woods and poor cuts of wood used that are marketed under 'name' wood banners YMMV, a lot.
Some of the worst tones I've had have been from trying to pimp cheap guitars with BKs. The very same pickups I got those horrible tones with sounded outstanding in better guitars. They let a lot of the guitars acoustic sound through and let the shiteeness through with it. I'd err on the side of caution and put less transparent pickups in a cheaper guitar, ideally EMGs, followed, imo, by dimarzio, then duncan, then kent armstrong, then swinsehead (the main pickup types I've sample seem to me to stamp their own sound on the guitar in that desending order). I use BKs for guitars that have strong acoustic performance, in which they utterly slay and cant be beat.
That doesnt mean expensive guitars or guitars made from highest class woods - it just means trust your ears when youre assessing the guitars acoustic performance. Your plywood body might sound great, it might not; we cant tell you that from across the internet.
