I’m sorry, do you know me then?
Beedster, you, me, anyone can pick up a bass and in five seconds know whether the rod needs adjusting with no tools. Explain to me why you wouldn’t want to know that before making any physical adjustment?
Reading between the lines, if that bass was on my bench, I would be thinking there is a reason the saddles are SO high. The OP says they are right at the top of the saddle screws which I would suggest is slightly unusual. My guess, rather than actually making any sort of adjustment, is that neck relief MAY be an issue and the previous owner has just raised the saddles to eliminate fret buzz rather than dealing with it properly i.e. adjusting the relief.
