I'm thinking of getting a USA Jazz or Precision in the near future and in looking around a local store noticed that the bridge pieces have grooves around them - about 5 like the designer decided that there will be inaccuracies in production so they'd like to have many different positions to put the stings and sort out sting alignment post- production. I am sure (hope) the real reason is to offer some flexibility in the string set-up by the player - but it still looks kind of rough as a piece of engineering. (Have we not moved fwds since the telecaster bridge design?) Am I being unjustly critical or do I just not get it? G & L seems sooo much better as a design to do the same job.
