The pup connections are via a plug-on socket - simple enough - I run mine without the original PCB and just extended the rather short original wiring - I consider the original switch configuration to be troublesome but not a deal-breaker at that price - they switched over in '79 to miniature switches, which is what I did to mine before I went minimal (1 pup, 1 vol, nowt else)
A much under-rated instrument...
They all came with their own cases at that time - I use mine to carry my Jazz at present, so that gives you a dimension...
They make beautiful fretless conversions, if that's your thing, too...
