What can I play instead of Bb7?

The nearest stand-ins on banjo that keep the same root are Bbsus4, Bbsus2, Bb. They keep the root and the fifth and only change what sits in the middle, so most songs still work — but check the swap against the melody, because the note you removed may be the one the tune is singing.
