I'm planning on overhauling the electronics in my bass once I have the money. The way I have it now (passive J bass), I have the standard vol/vol/tone then an on/off toggle before a side mounted jack. The toggle's not going anywhere considering it saved my glut hairs multiple times in church. I'm looking though possibly to add a black ice type distortion without losing total tone control, and seeing an old J bass with two double type pots controlling both tone and volume on each pickup got me interested in the possibilities. Thus, my plan right now is to have Vol/Tone-Vol/Tone-BlackIce-toggle-jack. Main thing right now is who can supply me with the appropriate parts? BTW, I'm a complete dunce when it comes to the names of different pot types, even trying to search these forums. If it matters, I'm looking to swap the stock pups in my bass with Dimarzio Ultra J's. Thanks for your paitence, and you're more than welcome to summon the flames of hell upon me for my ignorance.
