I'm not sure how correct this is, but this is my understanding thus far soft clipping emphasizes the lower order harmonics. Hard clipping has a mix slewed to the higher order harmonics. symmetrical clipping produces only odd order harmonics. asymmetrical generates both even and odd harmonics. The more asymmetrical, the more pronounced the even-order harmonics. I just wanted to know what you guys prefer. I think I'm looking for something that emphasizes lower even order harmonics mostly the second harmonic (octave) with the fundamental still being the dominate frequency of course.
