Correct. Overdriving a simple waveform such as a sine or triangle will result in distortion, but in a simple waveform this actually translates into adding harmonics...which is the same thing a waveshaper circuit is specifically designed to do via wavefolding, rectification, clipping, or basic ol' nonlinear distortion. With a more complex sound like drums, where there's not a specific pitch as such, this can result in a heavier, more 'crunchy' sound. Quite a few producers that I knew back in the days of the rave scene would use input preamp overload on their TR-909 kick signal to push that sound into the range of the fuzzy, semi-pitched BOOM that would make the dancefloor go crazy. In fact, if you listen to a lot of Aphex Twin's earlier work up to around the time he released "On", he employs a host of "bad/wrong" production and engineering techniques that wind up making a "right" in that it defined that crazed, ultra-hard acid sound he championed, most notably on his "Dice Man" and "JOYREX" releases.
