looks interesting.

Hmm, not so much a 'treble boost' as a 'bass cut'. At first glance, it would appear to operate by replacing a cheap capacitor with an expensive inductor, but there may be some sonic advantage to this approach. It's different, anyway.

The comment about hum pickup by the inductor no doubt explains why this approach is not used more often.
