Could anyone help me with a switch suggestion and the proper wiring of the switch??  I am wiring this in the remote section of a True-Bypass Switcher, as suggested by R.G., I have a few SPDT already, but I need some more and don't know which model to get and then I don't really know how to wire them so that they switch between V+ and ground.  Any advice would be awesome, the link this pedal was derived from is http://www.geofex.com/Article_Folders/rmtswtch/rmtsw.htm,  by the way, major thanks to R.G. for this amazing article

If you're using the suggested setup with the remote indicators, you only hook up the pole and one throw of the SPDT, so the switch conducts when you step on it. This requires the switches to be momentary.

If you're not using the remote indicating feature, just a switch on the input to the transistor driver circuit, you can hook up the switch so +12 goes to one throw of the SPDT, ground to the other throw, and the pole to the driver circuit. That way the switch selects either grounded (and off) to the driver, or +12 (and ON) to the driver. This approach needs alternate action switches.

R.G. Thanks for the reply, are you speaking of wiring the pole to the line in this pictuure, http://www.geofex.com/Article_Folders/rmtswtch/rmtsw3.gif,
labeled +on/-off?  And if so then I ground one throw and wire the other to the +12, correct, again thanks for the info.

R.G.

That's correct; pole to the on/off line, throws to +12 and ground.
