    The bass looks great, no fretwear or obvious signs that it has been tinkered with or modded.

    However, there is too much relief for a good action and the truss adjuster feels stuck. No give either way and I am not willing to turn any harder than I have already.

    It this common? Any suggestions as to how to get that sucker to turn?

    It is returnable but I really want this thing to work so all suggestions are welcome!

    Many of the MIJ's that I have serviced have had the truss rod adjusted to the limit. The problem is that nut can get jammed onto the end of the threads on the rod, and it seizes there. It needs to be backed off, removed and have a spacer washer installed to return to adjustability. This can be a problem, but first off - do not attempt to tighten the truss rod nut any further. If you can't back it off, take it to a luthier/tech and get them to deal with it. If they bust it the fix is on them. If you bust it .... well it's your problem.

    Fortunately it can be returned. I'll give it some careful effort but not paying a luthier. If the shop can fix it fine. Bummer, such a nice bass.

    Thanks for the reply. I was able to get the truss adjuster out. It was indeed maxed. Do you know of anything easily found that would function as a spacer?
