Seems to me he was straight with you. Due diligence is your responsibility.
I make sure I take the proper size TR wrench to insure there's no problem when I look at a bass I'm considering buying.
If I'm buying online, I ask those three little words..."How's the Trussrod?" and act accordingly depending on the answer.
Nope, my friend was assuming that because he was being so cool about getting me the better case and strap, that he knew about the problems.
I asked and he said there were no issues with the truss rod, but he also said "my buddy gave it to me up in Washington", so basically feigning ignorance.
I just got too trusting, also the drive to meet him, and the time he got off work, did not leave enough time for an inspection of the truss, since I had to be back in time to drop the case, and one of my other basses, back in storage, which closed at 9 with 9:15 latest time to get OUT of the gate. I have been locked in before in the past. So I was pressed for time. Perhaps it was an elaborate ploy to lure me into having to rush with the prospect of a better (condition) case.
But it generally is something I do, shine a light into it to see the hex walls, and give it a little feel with my 4mm key. I was in a rush this time and did not think about it this time.
But yes, I did ask about the truss. I also know the motivations to play dumb about a known truss issue. At the same time I can give benefit of the doubt. I did say I would clean his strings and let him meet me at band practice to get them, to save him $20, since the goth that was in his other case had no strings on it and a bridge in pieces.
I figure if I mention it, maybe he will offer a kick back. Either some cash, or perhaps that other case, which I would trade el crappo fender bag for, so he at least would have something to put his other bass in.
You are correct that I didn't do my due diligence in making the time to physically inspect it, and I should have done so when it was clear that the neck had a lot of relief in it, however I viewed that as me being close to where I was going to set it anyway, less work! I did my ear to the back of the neck, knuckle rap test and nothing was rattling in the neck, so the truss was at least not broken, but had I taken off the cover, shone a light in, and gave it a feel with a 4mm, I would have not bought it, or would have asked for a lower price. At the same time, I don't like to impose that, one guy selling an SX freaked out when I asked if I could give the truss a nudge to verify it wasn't jammed or freewheeling. he backed out of the whole deal (this was in text before going to see it which didn't happen of course). After that it has been a touchy thing. Not sure who was right, me or him? (SX guy)
The question is, do I text him about the truss, or just wait till he comes to get the strings and mention it in person?
It is not really a bridge that needs to be protected from burning, I don't need the guy to like me. But I would hate to have to be that guy who is stuck trying to sell a bass with truss issues.
Would the stewmac gripper likely be a solution that could keep the bass adjustable?
