Guitar pedal bypass

Hi to everybody,

it's my first post and I hope it is in the right section. I would like to ask help for a problem involving a guitar distortion pedal switch, I would like to have a bypass that gives as ouptput the same as input. The same thing as having two switches (one at the beginning and one at the end as in the lower drawing) but with only one. I think this could be done with a MOS but I don't know how.
