Hi Charles, thanks for making the subject live, although I may still disagree on some points
"Not true. Correlation does not imply causation. The ebow isn't changing it's response, frequency response of the pickup changes as you go from off axis to on axis. The sound is much "brighter" when you're over the poles. You can prove this by rotating a pickup away from the string, the tone gets duller. The ebow generates a lot of harmonics due to the clipping of the internal amplifier and the low inductance of the drive coil."
Not what I said. I was merely underlining the very interactive effect of using the E-bow on different part of the pick up which change with pick up (for example single coil vs humbucker). Indeed does the E-bow work the same way, still, type of pick up will - to the same technique- will generate different effects. It reflects the interaction with said mick and playing technique. Which does not mean the E-bow works differently. But resulst are way different.
"Also false. The "sweep arpeggio bowing" effect simply relies on the internal distortion of the ebow amplifying the slight vibration of the string and the motion of the ebow over the poles (causing the same brightening effect mentioned above), the strings are not excited by the ebow in this case, but by tapping with the left hand."
Untrue. I strongly differ here. It works simply with fingering a chord and then applying the Ebow. No left hand tapping required here. You can try yourself. The strings are excited by the E-bow, and reach immediately there resonance peak, which is the fingered not + clipping.
