Well, we have this message to go by:

Bypassing these two inductors will not impact your warranty.

By the way, I found an easy way to do the L4 deal. If you 
remove the left side panel of the K3, you can reach in and 
ground pin 7 of the mic socket to a little terminal on the 
board marked "gnd" with a piece of wire, and save the 
trouble of removing the front panel board.
