I got the 1610 for my Kemper and used the pick N' pluck foam inserts to get a good fit, but I'm curious if having the Kemper "knob-side" down is going to possibly put too much pressure on the knobs? i used some of the leftover foam to line the bottom of the case as the very bottom layer is harder than the pick N' pluck stuff. Having the Kemper face-down makes it much easier to put it in the case.
Alternatives to make it easier to grab when face-up are removing one side of the carrying strap and moving the strap in front of the unit, or using shoelaces or some other method. I'm thinking the carrying strap will wear out if I'm removing and re-installing it a ton over time
