Switch Doctor FS-2 Foot Switch for the Pearce G2x

I purchased a G2x used and it did not come with a foot switch. In looking for one, I came across the Switch Doctor who makes the FS-2 for the G1R and the bass preamp by Pearce, but he did not list the G2x as being compatible. I decided to take a chance and order one as I figured the switching between the G1R and the G2x is likely to be the same.
