ATELIER Z Electric Bass, 24 Fret Specification

I bought this bass because I admired Atelier Z, but my wife got angry and told me to sell it...
It was labeled as JHJ-189, but the knobs are slightly different, so it might not be that model... If anyone knows, please tell me.
I played it a few times with my home BOSS Katana, and there were no crackles or noise.

Below is information from the previous seller:

■ About the Product
This is a popular model, the JHJ-189, from the Japanese brand ATELIER Z.
It's a dual-personality bass that offers two distinct sounds, JB and H, with a single instrument.
The color is black. This is a custom 24-fret model, unlike the usual 22-fret models, allowing for comfortable playing in higher positions.
■ Sound Characteristics
It boasts a wide range of tones, from sharp slap sounds to rich bass tones.
• Mini Switch ↑: Front & Rear Pickups → Jazz Bass Sound
• Mini Switch ↓: Center Pickup → StingRay-style Powerful Sound
Despite being a passive model, it delivers a punchy sound and is versatile enough for any genre.
