This is a Mayones Jabba 4-string bass. Please refer to the specification sheet in the photos for detailed specifications. (Serial number has been concealed) It was made in 2023. I am the second owner, and I purchased it from a musical instrument store in September 2025. I fell in love with it and bought it, but I have too much equipment, so I am selling it to organize. I bought it in almost unused, beautiful condition, and since I have also kept it carefully, it is still in beautiful condition with no noticeable scratches, dents, or dullness on the metal parts. There is no warping of the neck. There is almost no fret wear. It weighs approximately 3.9kg, making it easy to handle. It can switch between passive and active modes, allowing for a wide range of sound creation and a broad range of applications. The preamp battery uses a standard 9V battery, but it also has a built-in rechargeable battery, and it is convenient with AUX and headphone jacks. The accessories are all included, as shown in the photos: the body, the original case, wrenches, lock pegs (strap side), and the specification sheet. (The orange cloth in the photo is not included) Please note that the buyer will be given priority even if there are comments. Thank you.
