Those cases are great. There was a guy selling a bunch of NOS Hamer cases on Ebay for something like $60 shipped, but they were for the Monaco (long scale). I have one like that that - lotta extra real estate up there by the head when the short and medium scales are in it.
That one is a nice fit with your EB0.
Neck joins the body at the 16th fret instead of the 17+ on my '60. That makes it difficult to hit high D on the G.
I never realized that, but this is probably why the Slammer feels so tiny next to my short scale B4S. Looks like on the USA basses they set the neck a lot more like the Gibson... joins at the 18th fret on the short scales, and the 17-ish fret on the medium scale.
Speaking of munchkins... I snapped a pic of the shortie getting dwarfed next to the beast you helped me chrome out!
