I have a lefty plywood Christopher 200 that I got from Bob Beerman. I'm really quite satisfied with it. It is well set up and plays fine. Amplified piz sound is not that much inferior to basses that sound much better acoustic and arco. But....of course a better bass would be nice. Unfortunately, my daughter has been looking at colleges, so it's not the time for a major purchase. In the meantime, what do you guys recommend for upgrades to the Chrissy? Bob upgraded the bridge and strings when I got the bass, so I'm considering tailpiece (has to be symmetric or lefty), wire, and endpin. I have not had any mechanical problems with the stock endpin. How big a difference in sound would an upgrade make?
