My reference to distortation was based upon the event where the spring not being isolated (or hidden) from the large amount of ambiant db .
Thus inducing a kinda feed back loop..
In a studio or test lab is one matter, but on stage the distortion is mega problem.... however, as already stated this type of (its all gone tits up waveform) can be used to create / stumble upon a unique sound (thats a swine to try and repeat)
