So after considering my options with short scale basses I actually ended up going the opposite route, I found a lovely used Fender precision bass, I think it is a Vintera.
Anyway, I tried it out and not only is it a looker but the action was setup nice and low (just a hair above 1.5mm at 17th fret), the neck is also one of the nicest feeling necks I have played and with a gloss finish which is nice because I'm not crazy about satin finishes, the neck is definitely chunky at thennut, the hardware all seems solid and the overall build quality is impressive.
The strings on the bass are flatwounds and I am fairly sure they are TI Flats as despite being flatwounds the strings feel low tension and very flexible for flats, not sure whether to keep to flats or change to rounds yet, if I go for rounds it will probably be nickel rounds as I want to keep the frets nice but I may change them to Labella low tension flats as they are slightly stiffer but are close enough in tension that I shouldn't need to adjust the truss rod
One question I have that I am hoping someone can help with... The truss rod is at the body end rather than the headstock end, does that mean the it operates opposite to a headstock end truss rod ie on a truss rod that is at the headstock end turning the truss rod towards the E string side of the neck tightens and turning towards the G string loosens the truss rod, is it the opposite of this with the truss rod as it is at the body end?
