In this paper we consider both Abelian as well as non-Abelian T-duals of theKlebanov-Witten background and inspect their various Penrose limits. We showthat these backgrounds admit pp-wave solutions in the neighbourhood ofappropriate null geodesics. We study the quantization of closed stringpropagating on some of the resulting pp-wave backgrounds and comment on theprobable field theory duals.
