A/B switcher with remote footswitch?

[Aentons]

Can anybody point me in the right direction for
a schematic to something like this?

Basically, I just want to switch my Vox Normal and Top Boost inputs and minimize any crosstalk noise while keeping the signal switching at the amp.



Edit: Sorry, I just saw that there is a Softie "Momentary Relay Bypass" listed as coming soon and realized that it is prob just what I need... that's good stuff
