Thinking about taking my first plunge into the world of hollowbody bass to explore some sound/tone ideas that have been bouncing around in my head lately. Looking for suggestions / past experience / help deciding on an entry level hollowbody. Got some free time to experiment undisturbed (the kids are going to Grandma's for the summer) and a budget of @ 400 - 600 bucks. New, used, or vintage? Appreciate any and all help.
