I don't see anything wrong with it. As soon as you have a pickup involved, you're into effects right there...
Whoa! I wouldn't go that far at all. For many of us, the holy grail of amplification is "the acoustic sound of the DB but bigger." No pickup is ideal and there are always compromises. Those are not "effects" as usually discussed because such effects are added intentionally. While the use of effects with the DB is definitely not for me, I'm with the folks who say, "If you like them, use them." To each (artist), his own.
