I second that! I used to own a MrBassman "No Sweat" model. MrBassman was a bass store in Frankfurt, that had their own basses made by two German luthiers. One was the guy behind Clover Basses, the other was Siggi Jäger of Human Base, who made mine. It had a beautiful Brazilian rosewood top with sapwood in the center, and it played great. I only sold it because the sound didn't really fit my needs at the time and I couldn't afford keeping it.
Does that BaseX have the neck that's bolt on deep from the rear of the body?
