I have a new Ibanez Artwood Guitar that comes with the EAS-VTC installed. I don't seem to get a tome change while adjusting the tone control at the edge of the soundhole.
I read in the manual that you can add an additional pickup by soldering the leads to a couple of pads on the endpin assembly. Is this when the tone control becomes active, to say balance between the under-bridge and a soundboard microphone? Or should it be working with just the LR Baggs underbridge pickup that comes with the EAS-VTC?
