What the hell is Mojo?
I am Scottish, I play folk, trad, bluegrass, and some country Americana music.
I searched wilkipedia for Mojo and never got an answer.
Is it some kind of magic or feeling, or is it a blues thing.
I think that the word gets used in here to describe things that have charm, character,"earthyness" or energy transfered to and from the instrument / builder. CBGs come from a blues background, at least in the USA, so references to magic/hoodoo/voodoo etc. seem appropriate, even if most of us do not actually practice any of these "religions" .
