270 Tunings

[Barry Schaede <barrys@xxxxxxxxxxxxxxxxxxxxxxx>]

My understanding of how the 270 chromatics work is that the key signature 
of the harmonica means the slide in posistion will be the next half step 
up.  For example if the harmonica was marked A the slide in would be A# 
or Bb.  Is this correct?  I've always wondered why Farrel offered an Eb 
270.  There must be a good reason or they wouldn't be avaialable.  Are 
there players who want to play in Eb without the slide?  What other keys 
does this configuration facillitate playing in?  Is the tuning Eb E?  My 
last weeks post on Farrel was in no way meant to discourage anyone from 
buying from them.  As I've said privately to others on the list good 
prices excellent value.  A combination that's hard to beat.  I'm eyeing 
the 270's and resigning myself to spending some $$ with Farrel again 
soon.  FJM
