Hey guys, I checked around and I might be stupid for not finding it but I guess I can just hope you humor me!=) In any case, I'm planning a warmoth build of a P/J bass on a tele style body with a jazz neck (long time dream of mine). So, I have the pickups, two seymour-duncan SPB-2's already, they were for another project that was thrown away. My question is, what else is necessary for me if I want to build a passive bass? I checked seymour duncans site and all the tone circuits they're offering are active. I know I should do copper shielding of the cavity, and I know knobs are necessary, but as far as making the pickups produce a tone what do I need and where can I find it? thanks again for not minding the ignorance and reading through this!
