Anyone know if and how I can toggle between my Mesa Boogie Studio Preamp and my SMS Classic..both powered by my MC50?

Also, I have a Loopmaster A/B/Y switcher that only allows one loop at a time. Can I use this to switch between the 2 preamps via the footswitch?

Any simple A-B box will do the trick with the correct cables. Would be best to keep the cables short and keep the AB box close to the equipment, not for instance run a pair of 12 foot cables back and forth from the back of the equipment to the stage floor. Actually simple!
