I seem to remember Mica saying this setup is known as the Series I.5 aka Series with a hidden humcanceller.
I also remember her saying they can't do it as an option any more, which suits me just fine. The more bits on show, the happier I am!!
My dream bass would have the Series II with a treble cut/boost and bass cut/boost knobs for each pickup, Laser LEDS with knob dimmer, and red+green side LEDS.
With an on/off knob.
