Help!

[LuckySeven77]

OK I just got a new second hand bass from some guy. When i got it the neck was slightly bowed, so i sent it to a shop and he helped me adjust it for free. the next week though, i found he relief was too much(in my opinion) so i want to tighten the truss rod slightly. My allen key fits perfectly into the truss rod, but i simply cant turn it. Anyone can help me on this?

Always turn the truss rod loose, before you tighten it. Loosen about 1/4 turn, then tighten it back in place where it was, and then proceed to tighten 1/4 turn. If it doesn't tighten, but only loosens, I'd bring it back to the tech.

Turn it back a little to free it then try retightening, remember 'Right is Tight, Left is Loose' as your looking at the adjustment nut face on, you want to be looking at quarter turns really, do not force anything, if it feels like it's going to snap...it probably will, also try standing your bass up and giving the neck a slap/push on the back (holding the head with one hand and the bass facing you up against your feet, you want to be pushing/tapping 'in' toward yourself), to try and free-up the truss, make sure your tuning is cool while you do this too.

Must reiterate don't force anything, give it back to a good Tech if it won't go with it.
