It has arrived and it's fantastic! No noise, no hum, no delay! Works straight out of the box! What means, I do not have to rewire, shield or do anything with the small Ibanez bass - no electrical connection - no hum! (Yes, I'm still going to play with pickups and might go the extreme way - high output Dimarzio blades + 500k pots).
