How not to distort bass frequencies with a Hard Clipping Waveshaper | Algorithm Design | Forum

I've made a wave shaper with a hard clip functionality. 

When I try it on the master channel, I see that the bass frequencies of kick are being distorted badly when the hard clip occurs.

But comparing to most of the saturation plugins, this bass frequencies sound better. Even there is a hard clip, the bass frequencies are not being distorted as bad as like mine (Yes they use hard clipping too).

So what is the tip for this? I am sure they are doing before the wave shaper or control it according to the input frequencies.
