I'm back from a trip to conklinguitars.com.. And I have a few questions about stringing. Is it right that the seven string Conklin Groove Tools is tuned from f# to B? Is it possible to get a good sound if you string it from c to F#? Would you be able to hear the low F#? Would it be too dark to hear as a tone and just be a rumble in the air like an 18-wheeler engine?
