Re: EBow - active/passive humbuckers
Hi Matthias,
Thank you for the question.
I consider myself to be an experienced user, as I have used an ebow
for nearly 30 years.
The principal of operation is apparently not well understood and
misinformation abounds, so I am trying to provide clarification.
As the drive coil of the ebow is brought closer to the pickup, it's
highly clipped square wave signal is induced into the pickup,
creating the characteristic buzzy tone. The volume will also
increase, but this does not mean that the string's vibration is
greater.
It's exactly like holding a police megaphone in front of a
microphone, you're hearing the increased amplification of the signal
through the cheap, clipped amplifier.
This is why I suggested the experiment below, using the ebow with the
guitar unplugged.

Chuck,
I do not use ebow
but reading you I get the impression that you try to convince
experienced users with theory...
why should there not be an interaction between the magnet fields of
the ebow and the pickup?
I do not see what your test would show?

I think people conflate the internal distortion created by the ebow's
amplifier with it's effectiveness at driving the string.
Here's a simple test anyone can perform: Unplug your guitar and turn
on the ebow. Move the ebow around the pickups. Do you hear any
difference?
