Actually Rex was the average guy in the bunch. At 19 and playing bass for less than a year I was playing his stuff. I couldn't do that for Cliffs or Ellefson's bass lines. We would have tons of bass players that could pull off the bass parts but to find a guitarist to pull of Diamonds part was a lot harder. The guy would have to be playing over 5 years or more. Plucking fingers would need speed but the fretting hand had little going on.
Yeah that's why I said together, Rex isn't the most technical player but he really clicked into the groove with the main man Darrell, so together they were freaking awesome. Not the best bassist, but with their powers combined

To ping or not to ping that is the question. My Forte is being refinished. Obviously I could choose the finish. In my humble experience the gloss finish "ping" can be heard unplugged. Plug the bass in and there is so much other stuff going on that you will not be able to hear it. In a matte poly finish the clear coat is not buffed to a mirror like shine. There is still clear coat there. Just not polished. I don't believe any of the colored mattes are actual oil finishes. I chose matte poly, though I reserve the right to change my mind and gloss that female dog!
