  We analyze the possible generalized CP symmetries admitted by the
Tri-Bi-Maximal (TBM) neutrino mixing. Taking advantage of these symmetries we
construct in a systematic way other variants of the standard TBM ansatz.
Depending on the type and number of generalized CP symmetries imposed, we get
new mixing matrices, all of which related to the original TBM matrix. One of
such "revamped" TBM variants is the recently discussed mixing matrix of
arXiv:1806.03367. We also briefly discuss the phenomenological implications
following from these mixing patterns.
