Description & Condition
Description & Condition
Crews Maniac Sound is a long-established Japanese brand loved by many professional musicians.
It is also known as a brand favored by Ryuta Sakamoto, Isaiah Sharkey, and others. (Titles omitted)
This is the JB Modern, a replica model of a jazz bass.
The body is made of alder and the fingerboard is rosewood, a standard wood combination.
While the overall design is traditional, the fingerboard radius is slightly flat, giving it a modern feel in various aspects.
The pickups are original single-coil pickups.
They offer the crisp sound characteristic of JB models, but with a slightly fuller and more powerful tone, making them highly appealing.
When combined with the original preamp, the sound becomes even more powerful and sharp.
This instrument offers smooth playability and an easy-to-handle sound, making it a highly attractive option.
Take advantage of this opportunity.
The remaining frets are approximately 85%.
The truss rod is firm but has been confirmed to move up to 90 degrees.
The neck has a slight bow in the high position and a tendency to twist toward the 1st string side. Currently, the string height is adjusted to 2.0–2.5mm at the 12th fret according to GIB standards. Depending on playing force, there may be slight buzzing in the high positions, but it is playable without issues.
The body and finish show scattered dents and scratches. The pickguard has noticeable scratches.
The electronics are in good condition.
A finger rest is installed.
Controls: Master volume (push/pull - active/passive), balancer, treble, bass
Nut width: 39.0mm
Bridge string spacing: 20.0mm
Scale: 34 inches
Manufacturing year: 2011
Manufacturing country: JAPAN
We use D'Addario EXL strings, which are trusted by professional musicians, during setup.
These strings feature a powerful attack and rich overtones, making them truly worthy of being called a standard.
These high-quality strings bring out the best in the instrument's performance and character, so please enjoy them together.
Adjusted by GIB craftsmen for ease of playability.
