I Have been a fan of the Kala U-Bass for 1.5 years now. I have owned 3, sold one, and another is going to the FedEx truck Monday. The third (my first) I will keep forever. A custom builder of all things P-bass and telecaster happens to live and work in my neighborhood. He is online at www.groveguitars.com. While consulting with him about commissioning a custom dream P-bass for me, I mentioned the U-Bass and things I and other would like to have in terms of custom options. It is hard to find, contact, and afford custom uke luthiers, so Scott and I brainstormed and have come up with ideas for building a custom U-bass that addresses some issues and voids in the current lineup from Kala. It will truly be a pioneering, one of a kind bass, and I would e happy to share the progress of the build. Disclaimer: I am not financially or in any other way affiliated with Scott or Grove guitars any more than being a customer, fan boy, and sharing ideas as an experienced U-Bassist, and collaborating in the design of my instrument. Scott is a great guy and a great builder and I can't wait to have the final product in my hands. It will probably be pretty soon.
