  We derive the spectral curves for $q$-part double Hurwitz numbers, $r$-spin
simple Hurwitz numbers, and arbitrary combinations of these cases, from the
analysis of the unstable (0,1)-geometry. We quantize this family of spectral
curves and obtain the Schroedinger equations for the partition function of the
corresponding Hurwitz problems. We thus confirm the conjecture for the
existence of quantum curves in these generalized Hurwitz number cases.
