I played 72-17 today and thought I'd share my impressions. I also took a few photos.
The bass looks in very good condition. It has a short scale type body with a long neck. String spacing is narrow, as expected. Slapping would be difficult, but normal finger-style was ok for me. Of course, I also play a lot of guitar. I sat with it and it was quite comfortable. I did not try it on a strap. The action was a little high at the body, but there was no string buzz, making think it could be lowered without any problems. The bass was articulate and good sounding, despite the strings appearing to be old. I could only play using one pickup, as there was no power supply with it. There was some hum present, but I was able to find a control setting which eliminated it. I also don't know the age of the batteries and I was playing through a very old bass amp they had. It comes with an old Guild case. Under the back plate were two large hum canceling pickups. I did not find a PF5 card but rather smaller circuit boards. Maybe Mica will give us more information on this unique and historical bass.
All in all, I really liked it
