This is a 5-string bass made in a private workshop. The brand name is not written anywhere, so the details are unknown, but it has a single-cut body, set neck, and uses beautiful wood, giving it the appearance of a high-end bass. The specifications are as follows (wood types are estimates): * Body: Flame maple burl top, alder back * Neck: 3-piece flame maple * Fingerboard: Pau Ferro * Tuners: HIPSHOT HB6Y-3/8 Ultralite Black * Nut: Warwick Just A Nut III 5string Brass * Bridge: HIPSHOT 5strings A Style Black .708 Brass (string spacing 18mm) * Pickups: Nordstrand Big Single 5 (18mm) * Preamp: aguilar OBP-3 * 3-band EQ knobs: Wood-carved knobs * Volume & Balancer knobs: Aluminum knobs Controls are as follows: * Volume (black aluminum knob on the neck side) * Balancer (black aluminum knob on the bridge side) * 3-band EQ (from neck side: High/Mid/Low) * Active/Passive switch * Mid frequency 400Hz/800Hz switch The neck is currently almost flat. String height is approximately 1.5mm on the 1st string and 2.0mm on the 5th string at the 12th fret. I tried moving the truss rod slightly left and right, and it moved without any problems. The weight of the bass itself was 3.9kg according to a health meter. There are some scratches and dents from use, but there are no serious scratches or cracks. The frets have only slight wear and tear, and I think they can still be used for a long time. In addition to the main body, a PLAYTECH hard case is included.
