  An effective Coulomb gauge Hamiltonian, H_eff, is used to calculate the light
(u-ubar-g), strange (s-sbar-g) and charmed (c-cbar-g) hybrid meson spectra. For
the same two parameter H_eff providing glueball masses consistent with lattice
results and a good description of the observed u,d,s and c quark mesons, a
large-scale variational treatment predicts the lightest hybrid has
J^{PC}=0^{++} and mass 2100 MeV. The lightest exotic 1^{-+} state is just above
2200 MeV, near the upper limit of lattice and Flux Tube predictions. These
theoretical formulations all indicate the observed 1^{-+} pi_1(1600) and, more
clearly, pi_1(1400) are not hybrid states. The Coulomb gauge approach further
predicts that in the strange and charmed sectors, respectively, the ground
state hybrids have 1^{+-} with masses 2125 and 3830 MeV, while the first exotic
1^{-+} states are at 2395 and 4020 MeV. Finally, using our hybrid
wavefunctions, dimensional counting rules and the Franck-Condon principle,
novel experimental signatures are presented to assist light and heavy hybrid
meson searches.
