Active SCPB? Does one exist? Are they possible?

I can't think of one. Active pickups are very uncommon anyway. EMG mostly, a few Barts and Duncans, that's pretty much it.

 

I don't think I've ever seen an active SCPB.

And you would need a rear-route, or a very very tiny preamp.

 

Why on earth would you want such a thing?

 

EMG

 

If you add in a buffer for the passive to lower it's output impedance, you can.

 

Why? What would you hope to achieve? What could an active single-coil pickup offer you that a passive counterpart could not, aside from the buffer for use with longer cables?

I think that if you tried to add the internal pre and buffer, you would likely just make the 60-cycle hum more prominent and annoying.

 

Nope. Impossible. Completely impossible.

 

Yes, it absolutely cannot be done!
Anyone that suggests it can is a fool! Don't let anyone tell you that you can do it, because you cannot!
It is impossible! Give up right now!

Ok guys, I'm off to my new job as a motivational speaker.

 

So, these guys are hiring you, then?

 

Do want.

 

Use an EMG S or SA pickup.
It's a stacked single coil and has a blade pole piece so it will work fine on a bass.
The S uses a ceramic magnet, and the SA uses an alnico.

And yes, you can wire a passive pickups to a preamp or buffer.

 

I was going to suggest the EMG strat pickups as well.
