I actually just tried it today with my accoustic... Just loosen the bow so that it can hit all six strings and put quite a bit of rosin on it (I'm sure this can't be good for the strings). All I could manage was chords, but that served my purpose. Like it's been said, don't use a quality bow because the ribs cant be good for the horsehair.
Also, the harmonics get a little harsh, so I am looking for different strings to use. Any ideas?
