This is a HISTORY ZJ-CFS jazz bass, an original brand of Shimamura Music, manufactured in Japan by Fujigen. It's a classic jazz bass style, offering excellent cost performance and suitable for a wide range of users, from beginners to advanced players. It features Fujigen's Circle Fretting System, providing a tight, clear sound and stable pitch. I believe it's a high-quality jazz bass that exceeds its price point in terms of materials and construction. If you don't mind the brand name, it's a very cost-effective instrument. Sound output has been confirmed. There are no noises or crackling that would interfere with playing. Please check the photos for the condition of the item, as it is a used product. Based on my amateur assessment, the neck has no significant warping, and the frets have plenty of life left. The truss rod has not been checked. The seller has not used this instrument, so the frequency of use is unknown. Fine adjustments such as intonation and string height should be made to the buyer's preference. Please understand that there may be some minor scratches or inconspicuous marks due to the item being used. The instrument will be carefully packed with bubble wrap and cardboard for shipping. The strings may be slightly loosened for shipping, as recommended by the shipping company. Accessories include a gig bag. The items shown in the photos are the complete set.
