First off, I've never heard it before... but I mite know your problem.

There are two possibilities...

if the harmonic is first... then choke up on the pick and make your thumb rub against the string, it takes time but you'll get it... then use the bar to your hearts content.


if the dive is first.... do a huge dive bomb and as you come up from it, lightly touch the string with your ring finger, and you should hear the harmonic (don't pick it!)


hope it helps!
