The use (and misuse of) directional cables has a big effect on my sound. I have my guitar wired with two outputs that I'm able to crossfade between. I have one cable going in the correct direction and another cable going in the opposite direction than it was manufactured for. The crossfader is pedal operated. I get some great contrasting sounds by crossfading between the two - sometimes people think I'm using a modified wah/filter/distortion/effect, but nope - just a simple crossfade between abused directional cables.
