Re: Why active pickups?

For me the value of having phantom power on-board my electric upright
isn't that I don't have to worry about fresh batteries, it's that I've
got a backup system for powering the bass if one of them fails or isn't
available (you can view the batteries as a backup for the phantom or the
phantom as a backup for the batteries).

Which is why 48 v is a problem. Almost all active basses run on either
9v or 18 v max. And if you do the battery shorter thing to inject
phantom power. 48v will be too much. But if your phantom power rig is 9
or 18v (switch selectable) then you can take just about any active bass
and short the battery clip and go phantom. Plus if phantom fails you
can put the battery back in and have that backup too. Which is what you
are saying. Personally I'm NOT a big fan of wall worts which are a
compromise at best IMHO. And two wires to a a bass definitely sucks (as
someone already noted). But as you note a separate phantom power supply
doesn't solve all problems because that now requries another thing that
has to be plugged into AC. If it's a wall wort that is even worse! But
now if your AMP has phantom power, then your bass "backup" source is
always right there (assuming you are using your amp). I think that was
the original discussion: Why don't AMPS have phantom power available
somehow for basses?
