Why don't you make an adapter for the base so the L1s could be inserted in reverse; then all the controls could be either in the front or back however desired. We have a small studio and the system has to be against a wall behind us. It's getting to be a pain when we're trying to experiment with different settings and presets with everything backwards behind the system. Or maybe put all the gain controls & presets on a bigger remote.
I'm surprised that I haven't found any other complaints on this forum about the location of the controls.
Anyway, just ranting a little after banging my guitar against the L1's a few times reaching around to make everyone happy with the presets.
