Dan... If you would recheck that post you would find the model I wrote about has
nothing to do with the "4th string" Bluthner.  Nor anywhere in my post is there a
hint of anything remotely connected with that 4th string. I give some
measurements for backscale lengths as well.

You might try fireing off post just a little slower. My experience is that on the
Tee as it were... the patient swing out performs the hasty one 98.6% of the time.
