I've got the same - also pimped with teacups! What do you mean by flip the pickups?
As for the strings, seriously, whack some flats on as soon as you can - it will bring the bass to life! Mine's got the Hofner flats with the dark green silks. Joyous thump.
Sorry to resurrect such and old thread but ...
I recently acquired a Hofner Ignition Club Bass and the Hofner Black Nylon Flats E-string (with the light green silk) doesn't fit through the tuner. Are you saying the nickel flats fitted OK?
