'Toy Bass' doesn't really grab my ear, and 'Double Bass' or 'URB' or some of the other names don't seem to convey the right grandeur for the big fiddle. This brings me to this proposal: The Bass (with capitalization) for, well, The Bass. The Slab for electric. Or, to borrow from some older players, simply call it 'Fender Bass' -- that should get a few Slabbists in a huff. ...and EURB? How about The Mullet?
