  Some properties of the non-commutative (NC) versions of the generalized
sine-Gordon model (NCGSG) and its dual massive Thirring theory are studied. Our
method relies on the NC extension of integrable models and the master
lagrangian approach to deal with dual theories. The master lagrangian turns out
to be the NC version of the so-called affine Toda model coupled to matter
related to the group GL(n), in which the Toda field $g \subset GL(n), (n=2,
3)$. Moreover, as a reduction of GL(3) NCGSG one gets a NC version of the
remarkable double sine-Gordon model.
