I used one on a harp track recently. It was in a fairly dense modern orchestration mix and the harp just wasn't cutting. I added (what I consider to be) a surprising amount on the track insert and it gave me a very interesting, slightly synthetic sound that really cut yet still suited the mix. Mind you this wasn't a traditional orchestra piece but something more along the lines of what you hear from Cirque du Soleil. The track ended up sounding more like a synth harp patch but it worked for what I needed.

I don't really think the thing qualifies as a "sounds good knob" but it has it's place in my toolbox (if not in my daily use tool belt).
