This is a 4-string bass. I purchased it new at the end of January this year and have used it to a certain extent, but I'm selling it due to a change in my equipment. I can provide all warranty documents. A bass guitar with almost the same specs from the same brand has clearly increased in price by tens of thousands of yen, so I think it's a good time to buy. Unfortunately, the specs I desire have changed... Please consider it after referring to the model name yourself. I purchased this bass because I thought it had specs closest to Victor Wooten's signature bass (Fodera) among the basses that are readily available in Japan. Depending on when you purchase it, it may take some time to arrange packing materials, etc. Thank you for your understanding. I will ship it in the new year. Thank you.
