No idea – there is a ½” difference in width, and I have no idea why – the nut width is the same. 175 (no cutaway) is a Swan spec’d guitar, so maybe its something he wanted? Its kinda odd, having the traditional diamond markers – maybe its more like a dread headstock? 174 has the ebony headstock, which feels more like a standard F cutaway detail. Maybe I’ll have to see if the shop has any other info on differences with these –
Lots o’ SCGC guitars! But never ask which is my fav
