So, I've got our bassists Curbow to restring and give a basic set-up and clean. Now, herein lies the problem. I could fit my wang between the strings and board on the higher frets, and the saddles are as low as they'll go.
Do I just need to tweak the truss rod a fuck load or is it something more sinister?
Without seeing how the neck relief is nobody could say if the truss rod needs a tweak. It might, probably does in fact, but you might also need to alter the neck angle with a shim.
Truss rod first, then check if the saddles need to move up. Shim neck as necessary.
Or.... have it set up by a pro
