An octave stomp can open creative doors in myriad ways—from adding muscle to your sound to unleashing octave-fuzz assaults, simulating a 12-string, and more.

Whether fattening up your clean tone, creating an all-out octave-fuzz assault, simulating a 12-string, or something just completely different, an octave effect can turn your guitar into a whole ’nother animal and inspire your sound crafting. We’ve rounded up a sampling of 10 solid options for you to get your octave on.
