Line selector question

[ggarms]

Hey guys

I recently snagged a really cool old Yamaha keyboard from the 80s with an awesome set of drum loop samples and had the idea of running it through my chain. Needless to say, it's been super fun! I got the idea of making  a simple line selector box so I could switch between either my guitar or the keyboard through the chain. I also occasionally use the animoog app on my iPhone through my chain to make loops as well, so having the ability to select between 2 inputs would save me some time. Any thoughts on achieving this? My initial idea was just to use an spst, outer poles being the tips of each in jack and the center being the tip of the out jack, tying all grounds together. But then my brain started working too hard thinking about an indicator led for each in and I've now confused myself in wiring diagrams for rotary selectors and feedback loopers. Any suggestions?
