1 Passive/ 1 Active
1 Passive/ 1 Active
How do you want the knob configuration, seeing as there are only 3. 2 volumes are a given. Which pickup do you want the tone to control because it can't control both. Yes, you will need a 2 way toggle. Give me some more info (new pickup) and I will try to see what I can come up with as far as a diagram.
Seeing as you don't use the neck pickup all that often I would say have the tone control the bridge. So your shopping list would be at: one 2 way toggle, two 500k audio taper pots. a .047 capacitor. you could use some of the wire that are already there. Of course the easiest thing to do is replace the neck pickup to passive.
If you don't feel like drilling extra holes, you can use stacked pots. EMG makes a 25K stacked one, Im sure you could find a 500K one elsewhere. Thus, you get a separate tone and volume per pickup.
"I just can't remember how ESP wires the ground to the bridge on the tune-o-matics"
Doesn't really matter. For active pickups, the bridge is NOT grounded at all. For passives, just tie it to any pot casing, or the selector switch ground.
Runs the risk of reverse polarity shock as I said before. Actives are internally grounded, so by connecting your strings to ground, you can somehow damage the EMG's. This is plastered all over their site as well as their schematics. Im a programmer, not an electrical engineer, so I dont know all the gory details.
i never was told to install the preamp circuit when i ran a hot rail w/a hardwired 81. you just need to give each pup it own volume pot. actives run on 25k, then 500k for humbuckers, and a 2 or 3 way switch. you can use the ground wire for the passive. i'll hop on the old pc and scrounge up the schematic the emg tech made up for me.
+1. I've been curious about it. I've seen a few guitars that way. I'd think you may lose the "middle" toggle function though. Most people do it with a mini 2 way toggle deal. one OR the other ya know?
