  We study the stochastic background of gravitational waves produced from
preheating in hybrid inflation models. We investigate different dynamical
regimes of preheating in these models and we compute the resulting gravity wave
spectra using analytical estimates and numerical simulations. We discuss the
dependence of the gravity wave frequencies and amplitudes on the various
potential parameters. We find that large regions of the parameter space leads
to gravity waves that may be observable in upcoming interferometric
experiments, including Advanced LIGO, but this generally requires very small
coupling constants.
