Moon Electric Bass PJ-4 Full Maintenance Old Logo Crescent PGM 90s

Moon Electric Bass, likely a PJ-4.
I received this about 25 years ago from an acquaintance.
This item is being listed from Kanagawa Prefecture.
If you pick it up directly, I will offer a ¥10,000 discount to cover shipping and handling costs.

Condition:
There are some dings and minor rust on the metal parts, but no critical issues with the overall condition.
I barely used it after receiving it, and it has been largely unused for the past 25 years.
As I am not very knowledgeable about musical instruments, I had it fully maintained at a music shop for the best possible service before listing it.

Maintenance Details:
Neck adjustment
String height adjustment
Octave adjustment
Fingerboard and fret cleaning, nut groove cleaning
Overall cleaning, parts cleaning, and noise reduction

Strings have not been replaced.

Since it was originally owned by someone seriously involved in music, there are several modifications to the body.
The original passive pickups have been replaced with active ones, so there is routing done under the pickguard.
Also, as shown in the photos, there is a hole in the pickguard, though I'm unsure if something was originally attached there.
The currently installed pickups are EMG.
There may be other modifications, but I am not aware of them.

Nut width: 38mm
String height: 4th string → 2.1mm
3rd string → 1.8mm
2nd string → 1.5mm
1st string → 1.1mm
Weight: 5.0kg

Please consider this item with the understanding that it has been previously owned, was heavily used by its previous owner, and has been modified.
If you have any questions, please feel free to comment, and I will do my best to answer them within my knowledge.

Thank you.
