Pitch Bending Natural Harmonics

[SonofJud]

Hi, I was wondering what technique to use to effectively bend pitch and apply vibrato to natural harmonics. The only techniques I can think of are either bending the neck of the bass(probably not a good idea), fiddling with the tuners(not as efficient as I would like) or using a whammy bar(which I don't have). Sorry if this is in the wrong forum, I thought perhaps one of you solo bassists might know how to do this.
Thanks

I've bent the strings from the tuners' side of the nut for a vibrato / bending effect on ringing harmonics. Works pretty well. Set a ringing harmonic on your G string for example and push down on the string beyond the nut to get an idea how much pressure you have to apply for the effect you want.

This is usually a fretless technique. A common way to pitch bend a harmonic is to play the harmonic and then depress the string to the fretboard and do your movements there. As I said it works best on fretless, but can be done on a fretted instrument to some extent.

Also, you could depress the harmonic onto the fret on a fretted instrument and play the vibrato up and down as you would any other note on a fretted bass. The trick is that you will need to keep your finger over the fret as you do it.

You could also use a d-tuner to shift a harmonic as well, with the obvious limitations.
