Plywood...Really? Is this being said only because the application is Metal?
Meh, whatever...
As fans of a company that offers so many choices...it's more than a bit misguided to state that something as fundamental as body wood will make NO appreciable difference. Is that not the point of so many varied offerings? Because it makes a difference? For that matter, why then do so many of the board members choose to build with exotic woods? Is it for their tonal qualities....or is it because they are attractive?
I'm not being sarcastic on that...really...WHY pay extra for a special wood unless it MAKES A DIFFERENCE...and if it makes a difference then it makes a difference to the way that instrument sounds, no matter what genre it's being used for. Unless you feel different body woods are offered just for good looks.
Of COURSE electronics are going to be a vital part of the sound as well...but...let me put it this way...you can wear my shoes, but I'm still faster than you!
Oh...and the gloss black finish on my solid Koa Gecko is black as nightmare! Shiny and unyielding!
OP, You've chosen wisely.
