Switcher between front and fx loop of amp.

[KoskineN]

Hey guys!

I would like to build a box to switch some pedals between the front and fx loop of my amp. Some builders already do some,
but it looks like an easy build, and I want to build a box that cover my needs in term of size/layout.

Any ideas/schematics/plans around?

Thanks!
