One other option is to re-arrange the GK pickup 8 pin connector inside the gk blob with the volume knob.It looks like I might not be able to mount the GK-3B on this bass due to the volume knob and lack of clearance from the strings to pickup.
Has anyone been able to work around this type of issue?

Mount the pickup one string space up, so 1/3 of the pickup os above the E string.
In the 8 pin plug are two ground and 6 pickup wiring pins, extract the 6 pickup wiring plug pins so that the order is moved along 1. That way the GR-55/SY-1000 can still have the GK setup seen as a regular 4 string, you may need to try normal or reverse gk mounted options in the menu.
