How do players like Jaco, Wooten and Manring get such great volume whenever they hit a harmonic? When I play a harmonic regularly with my fingers, its usually very quiet. The other option is to strike it with the edge of my fingernail. Doing so gives a nice loud harmonic, but it can be awkward and uneven sounding. Turning the volume way up can allow me to pluck harmonics regularily. Is this what those legendary players did? Just crank up the volume? input anyone?
