This is a nice looking bass. Based on the K serial number it was apparently ordered as an Essence bass but with a different body style and Signature electronics.

oooo!
that's pretty 😍
alas.  no LEDs. 😟

I declare, I've seen that bass before... it's been a couple years. The K code is the trigger. My Custom fretless 5-string was ordered as an Essence too.

*I ain't crazy... just... uhhh... special.

Here is another one on Reverb from CME that is also an Essence with Omega/Balance K body shape.
They have it marked as a Mark King Deluxe though.
And good news for BeenDown139... IT HAS LED's!!

oh wait, the price is astronomical!! Cool though, Essence with Balance K body, Signature electronics and LED's.
If only they had it marked correctly.
