[CAUT] St. D Aliquot bar specs

[Rob Loomis]

Thanks -

I've got 2 70's D's and 2 brand new D's with so many problems that I'm just trying to tack down any original intentions. 

My understanding has been that the back string does not send energy back to the speaking length but that if those lengths are 'in tune' they can help give a more full tone by ringing sympathetically with lower partials. Any possible truth?
