I have the Kingfisher SE - I've had it since feb 2017.
It's an incredibly well-built and to my eyes, beautiful-looking instrument.
Some have mentioned concerns about the quality of the tuners - I have no complaints - they're Hipshot HB6, the bridge is a Hipshot TransTone. The pickups are treble & bass humbuckers.
My only niggle is that the output is quite low. I queried this with PRS:
The Kingfisher bass has very low output pickups so it doesn’t sound like they are faulty. Despite looking like humbuckers one of the coils is a dummy coil and only there for noise reduction, consequently they have the output of a single coil. In the development stage it was found that they sounded much better as single coils.
I use it with EHX Mole boost pedal, and no worries.
I'll post a pic when I get a chance.
If anyone is interested, I can bring it to the Midlands Bass Bash.
