Here is the final product. I still have to wire it up, but that should only be a couple hours.

So, this is just the completed chassis but I intent to start wiring it up tonight. I am using the knife switches to send 5v to the input relays. here is the scheme for the relay and my questions is, where does the ground go on the relay? I am building a regulated PS that will put out the needed 5Vs so should I use the ground on that circuit or the ground for the preamp or does it matter?

Note the protective reverse diode. Pin 2 of your relay gets the V+ supply voltage, then grounding the other end of the coil energizes it. That would be pin 6.
That assumes the diode is included inside the relay. If the diode is something added outside - as is usually the case - then either end of the coil can be either place. Pins 2 and 6 are the coil. One end to V+ the other to ground. To snub switch arcs, we want a reverse wired diode across the coil.

Hi,
Just a suggestion for you next project that you need to use switches. You can use large magnetic reed switches and a magnet to close the contact. Do a search in EBAY using the following description : Reed Glass Magnetic Switches LARGE 36W 50mm NO SPST . The bigger the better. It will look nice.

- anyone use knife switches for input selection???
