  We study the gravitational signatures that arise from compactifying Type IIB
supergravity on a compact space containing a Klebanov-Strassler warped throat.
After reviewing the dimensional reduction of the 10d graviton and explicitly
obtaining the equations of motion for the 4d tensor $h_{\mu\nu}$, vector
$h_{\mu n}$ and scalar $h_{mn}$ modes, we find the masses and wavefunctions of
the Kaluza-Klein tower of spin-2 states. We explore how the masses and
wavefunctions depend on the balance between the strength of the warping and the
size of the bulk, and how these relate to the range and strength of the
interactions which correct the Newtonian gravitational potential. By computing
the modified Newtonian potential for sources on a brane somewhere along the
throat, and applying consistency constraints on the Klebanov-Strassler
parameters, we obtain predictions for the phenomenological parameter space. In
the case of a fully warped throat, and depending on where the brane is along
the throat, these predictions are narrow in range and consistent with current
observational and experimental constraints. We also begin an exploration of
gravitational wave signatures of KK gravitons in warped throats, finding that
strong warping can bring the corresponding frequencies down to the windows of
current and proposed experiments.
