Too bad about the bridge, even if this one is LOTS better in terms of adjustability and stability! It looks off, especially with the plastic covering up the routing. If you'd ever replace it with a Rickenbacker or Hipshot bridge, you'd still be able to see those 4 screwholes

Probably an old replacement though, from before the Hipshot was available.

If I were to replace a Rickenbacker bridge today, I'd probably get the new adjustable Rickenbacker bridge or wait for the Babicz that drops into the original tailpiece.

Nice wood on the 4001
