  We analyze light vector and scalar meson mass spectra using a novel approach
where a modified soft wall model with a UV-cutoff is considered. Including this
cutoff introduces an extra energy scale. For this model, we found that the
masses for the scalar and vector spectra are well fitted within a very small
RMS error for 14 of these states, with non-linear trajectories given by two
common parameters, the UV locus $z_0$ and the quadratic dilaton profile slope
$\kappa$. We concluded that in this model the $f_{0}(500)$ scalar resonance
cannot be fitted holographycally as a $q\overline{q}$ state since we could not
find a trajectory that included this pole. This result is in agreement with the
most recent phenomenological and theoretical methods.
