Ok, joking aside. I've just put my 4-string P-bass into a Hiscox. On the tuner side, there is, on mine a good amount of space. Where the +1 tuner would be, there is a reasonable amount of space. This space varies as the bass can move a bit.
The tuners on mine project about 45mm from the side of the headstock. It's possible that the space in the case, at the other side of the headstock could be about 45mm, but the tuner would be permanently against the side of the case. If you're looking for a case for general carrying about, it would probably be ok. If you're looking at this as being an insurance against damage if it were dropped on that corner - find another case.
