Custom DR Heartfield DR-4 late-80s Black Pearl

I inherited this bass. I'm moving and I unfortunately have no room for it anymore. Very versatile sound. They don't make these basses anymore. If you aren't familiar with DR Heartfield, there is a ton of great info here:

Technical specs: Serial number J10013. Most likely made in late 80's. DR-4 Heartfield 4 string bass in "Black Pearl Burst". Active and low-z output. 22 Frets. Single Truss. Standard 1/8" and XLR output. Made in Japan. Missing a knob and has a few minor dings. Otherwise works great. Comes with case. Requires 9v battery.
