Re: Jb/59 for metal?
I never understood the logic of wanting to purchase new pickups before even knowing how the originals sound in the guitar. Due to the differences in each piece of wood, it can be a total crapshoot and miss the mark completely, seen it happen countless times both on this forum and in real world retail situations.
And if you like what you already have, then you might wind up stuck with 2 brand new pickups that you don`t have a use for and end up selling at a loss, depending on the return policy of whoever sold them to you.
Wait until the guitar arrives, play it for a few days with your setup, and THEN decide what you don`t like. That way you know what you have, and where you want to go from there, instead of having to base the entire plan on pure assumptions of what the guitar will sound like. Simply because there are slabs of ash out there that are darker than mahogany, and mahogany that`s brighter than maple, and that´s why you can only make ballpark guesses / broad generalizations about the expected tonal response without actually holding the guitar in your hands.
