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

Question:
I have a 1970-s sunn studio lead amp with this type of rca jacks in the back for the reverb tank. Will this switch work? Thanks

Answer:
The RCA jacks you are referring to simply connect the physical spring tank to the circuit of the amplifier. Plugging a footswitch into them would have no effect. It is not advised that you do this.
