This is a jazz bass type model from Hachigen Kobuta, a workshop located in Osaka. Unlike the So What model, which is widely available in the market, this is not an OEM product. It's a handmade model crafted in the Hachigen Kobuta workshop, and they are currently not accepting orders for Fender clones, making it extremely rare. The sound is simply a high-quality jazz bass, with the thick low-mids and the gritty highs that you'd expect from a jazz bass. There is a demo video of this specific instrument on the Geek In Box YouTube channel, so please refer to it for the actual sound. I was very fond of this bass, but due to unexpected expenses, I am selling it to raise funds. I will remove the listing if my financial situation improves. The original hard case and warranty are included.
