In the recorder family, the great bass recorder has a range starting at the C below middle C (that is, the viola range). Instruments in this range provide much-needed bass support for wind ensembles.
Because the recorder's size necessitates keywork, which must be made precisely, commercial great bass recorders sell for $1000 - $2000. Now you can create your own for about $30-40.
Note: the prototype in this video reflects an earlier revision of hole placement. The revision in this Instructable features better tuning.
