'Nother stoopid Q.
Scott that is kind of a strange question. To help me answer your question I have a few of my own. 1 do use your rack gear strickly for guitar? 2 Is your rack in a set configuration or do you like to pull things in and out as you please? 3 do you play out with your rack?
See because if you only us your rack at home and you do not like units that color your sound in the signal path when you are not useing tham than yes a patch bay could help. *You see with the patch bay basically you just plug the ins and outs from your unit into the back of the patch bay and than use patch cables to connect unit to unit on the front of the patch bay. In a guitar rack a patch bay only really save you from having to go in back of the rack. Now in a studio envirment they are key.
I hope helps a little If you have more questions I can go into more detail.
