I don't recall anyone ever mentioning things to watch out for but then again I don't remember too many specific comments about the D'Armonds. I suspect you are over analyzing things, a trait I share.
I do have two comments. Is the price low enough that you can afford to make a mistake? How many dinners out would you have to give up if you bought it and it was a total loss? Is it high enough that it would not be much more to aim for a used Newark Street Starfire (~$700) instead?
Good thoughts, fronobulax. I'm starting to learn the bass after a few years learning guitar. This DeArmond bass is attractive for reasons of the classic Guild design, semi-hollow construction, and DA reputation for high quality builds out of Korea in this period.
The asking price is $650 plus shipping, described as excellent condition with controls working as intended, and includes the DA HSC. The seller is out of state, so it would be a leap of faith based on his condition description, and a gamble that I would end up with a classic bass in excellent condition.
I confirmed a transaction on Reverb for an almost identical guitar and case for $550 plus shipping two years ago, so that sets my benchmark. It would injure my pride more than my finances if I had to have remedial work done or re-sell as a museum piece. I set the budget for my first bass at $500, but am considering the Starfire for the reasons mentioned above. Otherwise, I'll probably end up with an Ibanez, G&L, Schecter, or PRS that falls in my original budget (and maybe save up for a Newark Street Starfire II).
I appreciate all the good input, I just need to make up my mind!
