The second one is standard and the first is the sig one. Is there a difference in sound between the two? If not then I was going to go standard but if the first gives maybe a more metal sound (not just look) then I can justify buying it. It seems the only real difference is that the sig can hook up to two amps, which is kinda dumb IMO.

Anyways what do you guys think?
The KFK has two outputs so you can use it in stereo but besides this they are identical
