For any $2\le n\le \infty$, we construct a concrete 1-parameter family of non-orbit equivalent actions of the free group ${𝔽}_n$. These actions arise as diagonal products between a generalized Bernoulli action and the action ${𝔽}_n\curvearrowright ({𝕋}^2,{\lambda }^2)$, where ${𝔽}_n$ is seen as a subgroup of ${\mathrm{SL}}_2\left(\mathbb{Z}\right)$.
