Overdrive
There's no hard line that separates overdrive from distortion from fuzz. They all kind of hang out in this nebulous world of spillover from a auditory standpoint. If looking at the manner in which the signal is manipulated to get the "clipped signal", it might be easier to arrive at a place where the distinction between the terms makes a difference.
Overdrive, as we understand the definition, is a clipped instrument signal, typically with only one half (the bottom half) of the waveform of the music signal being clipped. This results in only even-order harmonics being generated. Also characterized by a "soft" type of clipping applied to sine wave with the edges of the clipped signal being rounded as opposed to hard-angled (when viewed in an oscilloscope).
