So, I have a Squier Standard Jazz, which i got a couple years ago, and since I'm getting a new bass, i figured I should just mod this one to make it a little bit better. So far, what I have planned for it are:

a set of EMG-J active jazz bass replacement pickups, because I want something with higher output than the stock pups.

A badass II bridge, because the stock bridge has crap sustain

A mirrored pickguard that matches the chrome control plate, because that would look f-ing sweet

And that's pretty much everything I have planned for it, at least for now. If anybody could give me their opinions on the pups, or can think of something else I can replace, that would be great. I play mostly thrash metal (Anthrax, Megadeth, Metallica, etc.) and more modern metal (Lamb of God, Children of Bodom) so you guys can kinda see the tone I'm goin for with the pups.

Question; how many extra knobs do you get with the emg:s? Will you use concentric pots for that?
I have no idea what I'm talking about. Don't belive me.
