Source changing switch for an amp

I have been in the process of looking to do a DIY amp but I don't know much so I am starting off simple using the guts of a RS deal of the century amp.
Basically I would like to add a source switch and replace the front board controls with just a volume control/pot. And would it also be possible to create just a straight through to the amp source.
I have not been able to find any source switches or I am not looking for the right thing. And are there any other resisters or op amps needed to do this?
