OK bro. Re read my post slowly. In it I state the truss rod is broken. i also said there are minor scratches. i also state the pics dont show much.
I did not post this to argue with anyone. i gave you all the info i have. if it isnt enough for you, sorry. thanks for looking.
Dude, even post #4 started by asking you if the truss rod is broken, so maybe you're not being as clear or providing as much info as you think you are.
You get out of your query what you put into it. The rod could be frozen, or the nut could need replaced. If so, a competent tech could salvage the neck and save you the cost of a replacement. Or, the rod could be snapped, meaning the neck is probably ruined and a replacement is your only option.
Like I said, when it comes to truss rods, "broken" could mean a lot of different things. It helps us answer the question if we know more about why the rod isn't working. If you don't know, I suggest you ask the seller for more information and get back with us.
If the rod can be salvaged, you need to factor that cost into the overall price you are willing to pay for the bass. If the rod is snapped, and you still want a loaded body, you will have to factor in the price of a new neck and hardware and a tech to help with the install fret level and set up.
I would pay up to around $150.00-$200.00 for a loaded MIM J body.
You can get a decent loaded replacement neck for around $150.00.
See how much more complicated your question was than you thought? You have a lot of very experienced people on this site willing to give you good free advice, but it pays to play along and show a little respect and appreciation.
