I have tested the sound and operation of the bass amplifier. Volume, tone, tuner, etc. all function normally. There are no issues with the operation of the tuning pegs or plugging/unplugging the jack. The neck and fingerboard show some signs of use, but there are only minor scratches on the back of the body, and there is no damage that affects performance. Overall, it gives a clean impression. Please replace the batteries and strings as they are consumables. Equipped with a piezo pickup system. Easy sound making is possible with the preamp at hand. It also has a built-in tuning meter, making it a practical design. Tuning is E-A-D-G from the 4th string, the same as a standard bass. Combined with the unique thick strings, it produces a powerful tone reminiscent of an upright bass. Surprisingly powerful bass sound is produced from the small body. This is a set of the main unit and a gig bag. The strap in the photo will also be included as a bonus. Although there is no original box, it will be shipped in a waterproof plastic bag, packing material, and a recycled cardboard box. * The description of the condition is subjective, and there is a possibility of oversight. * Please consider this as a personal transaction of a used item. * Please feel free to contact us in the comments section if you have any requests.
