I was thinking about if it would be possible to mod the ebow+ and install it into a guitar in mid position with a sliding bar of some sort and a quick screw type lock.
My concerns are getting it close enough to the strings without affecting playability and if it may create any unwanted noise?

What say you UG?
Not much interest here. The sustainiac does not have harmonic mode, which really adds a nice range to the ebow+. I think for this to function properly I would need a rising platform on the slider as the ebow needs to be extremely close, and may ruin playability permanently in useable position.
No, the Fernandez Sustainer does have a harmonic mode.

What you're trying to do would be over complicated for no reason.
