Yes, even though this is clearly marked as possible on Doepfer's own website, the bolts supplied are too short. When mouting these brackets on the lower part of the LMS9, the bus bar bolts protrude from the case which makes the bracket sit proud off the case and therefore, the bolts supplied cannot reach the captive nut inside the case. So I have to go hunting for the current length bolts now.
I will point out the bolts supplied seem the wrong size for the holes which does allow for lots of alignment capability but doesn't seem right from the "sense of security" point of view.
Either way, null points, especially how expensive they are.
