Some basses need adjustments after a string gauge changes, some don't; it depends on several factors, including player's preferences. I'd keep an eye on the bass and see if you can see, feel or hear any differences after a few days then decide if you want to have the bass adjusted.
If you changed to a heavier gauge, it is likely that your bass' neck will gain a little relief (because of the increased tension), and may need the intonation adjusted forward (towards the neck) just a little (also because of increased tension). Additionally, since heavier gauge strings are under more tension and will thus have a narrower vibrational pattern, you may even be able to have your action lowered slightly (maybe).
If you changed to a lighter gauge, the neck may lose some relief and the intonation may need to be adjusted slightly backwards (away from the neck).
Truss rods are fairly easy to adjust if you've got the right information, but at the same time they can be relatively easy to break or damage as well (and that's a pretty expensive repair). It is possible to learn how to adjust them on your own.
Yup, the Thomastiks are pretty nice all-in-all. |
