I can't tell you the number of times I wished that my distortion box had separate outputs for hurt and pain. It's so frustrating having to convey hurt and pain mono summed through the same 1/4 inch jack.
Essentially people are collecting pedals out of emotional attachment to an artistic presentation or obsession with improving their guitar playing with perceived instant shortcuts to the best possible guitar tone.
Yep. I find that hurt is more focused around the 800 Hz area, whereas pain is between 2 and 4kHz usually . . . different speakers can better emphasize these frequencies.
