I am relieved to know it wasn't just me! I find the A20s much more comfortable. Yes, 3-screw adjustments on both. Here are some shots of the BBR. The trem cavity in the back is empty and unmarked, so presumably they decided to use the Wonderbar late in the process. It is the best trem I have used but my experience is limited.
