If anybody's interested, here's what I got back from Fred Hammon, re: Dark Star pickup in Epi JC Bass:
It's been done.
You will have to dispense with the veri-ohm switch circuit as it will
be irrelevant. That only works with low impedance pickups. One of
these bass (shown) owner replaced his switch with a producers knob -
a knob which does nothing but gives the operator a sense of
involvement - a placebo control knob.
You may also to elect to install a veri-tone pot under the control
to get actual tonal changes but I suggest keeping it simple. In an
instrument like this, less is more. Rely more on right hand placement
and dynamics.
The Dark Star will still allow the bass to speak with it's own
signature voice but with a broader, more open sound. A bit less
accent on the mids - more of everything - just bigger.
