Well, Alex, hmmm, it has a p-r-e-t-t-y-*-s-m-a-l-l soundhole, so one would have to be shoving a mighty small thing, and then the soundbox is pretty small too, so whatever you managed to cram in there would not go very far.

But now that you mention it, I have never tried blues on it; maybe I should give it a go. Then I can be a Psaltery Dog!
