if you have a 1cm gap on the guitar.... go and challenge people on the forum for a neoclassical battle... and winner get to smash that guitar on the loser's head. :mrgreen:
small gap is ok lah. when i mean small is less than 1mm.
Tonewise... you may or may not hear a difference but a well built bolt on guitar should not have gaps.

There are many vintage guitars with small gaps, some can even slip name cards through the gaps.
