Footswitch Box - Fender®, Two Button, Vintage, RCA Plugs

Question:
I have a vintage 70's era Fender Twin Reverb. There are two inputs in the back for pedals; one for reverb and one for vibrato. These inputs are smaller than the inputs on the front for guitar chords. Would this be the proper pedal for me?
