Ended up getting the SBK-3AD. I'm a little confused with the connections though. The site says "Simply connect your (2) pickups to the NO SOLDER terminal block (neck~shared ground~bridge) on the balance potentiometer or simply remove the potentiometer and wire direct for single pickup applications". I have three different grounds, one off of each pickup and and coming from the bridge. At least I'm assuming it's the bridge but I haven't taken it off to verify. Are all three supposed to go in the middle terminal?
If that is the case I tried but couldn't get them all to fit.
