Aria Pro II Semi-Acoustic Bass (Model Number Unknown)

This is not a recent model. When I contacted Arai Trading, they replied, We cannot confirm, but it is believed to be a model produced in small batches in the early 1990s, possibly made by Matsumoku, but this is not certain.
There is no manufacturer's serial sticker inside.
This is not a modified TAB series, but the original pickup configuration.

The neck has a rosewood fingerboard and a long scale.
The only AriaProⅡ logo is on the machine heads.
One of the tuner's back covers is missing.
The front pickup has been replaced with an Artec EBC4 Ceramic Sidewinder Mudbucker style (30K). (Mudbucker style pickups are about 5mm thicker than standard, so the cavity has been slightly enlarged. Conductive paint has been applied.)
The rear pickup has also been replaced with an ALLPARTS PU-0419-010 Bass Humbucking Bridge Pickup (11K).
Pots are Volume CTS250A x 2, Tone ALFA ALP-500B x 2.
Capacitors are F 0.047 Vitamin Q, R 0.033 (manufacturer forgotten), one each.
The jack is a Switchcraft 12B.
All wiring, except for the pickups, has been done with vintage cloth wire.
The reason for rewiring is that normally both volume and tone are 500A, but the tone control was not very effective, so this combination was found to be the best after various trials.

There are scratches commensurate with its age, but I don't believe there are any major scratches or cracks. (There is a slightly noticeable scratch on the back of the body.)
The weight is approximately 4.25kg.
The truss rod has some tension but still has room.
Currently, the rod has not been adjusted and there is a slight forward bow.
The original front and rear pickups will be included.

If desired, it can fit in a KIKUTANI GVB-60EXV case, which can be included for an additional 6500 yen.
