On the Chet Atkins signature acoustic-electric, what type of pick-up is that in the soundhole?
2 High Sensitive Filter'tron™ Pickups
no, on this one:
Looks like a plain ol' Piezo to me.
anyone know where I can get one that covers the entire soundhole like that?
Perhaps Guitar Center (you guys have those, right?). Check around music shops; if a store stocks acoustics, chances are they also have a variey of Piezo's to go with. Also check Musicians Friend and other such online shops.
