Thanks again for all the quality, well-thought out responses folks.
Not that anybody touched on it, really: not suggestively or indirectly, but, just want to ensure folks I am far from an investor! I am not smart enough with money or valuable things, to be one. (If I was, I may have kept that 1986 Fodera I bought new...and sold in 1987. OK, I was a kid and didn't realize the mistake, but nonetheless...stupid move.)
I am a player, that's all I will ever be bass-wise. I can't really afford to collect, but I have some instruments I love to look at

ALMOST as much as I love to play them. But it just dawned on me, that I am the original owner of a Japanese-crafted 1987 Ibanez, that I bought new for $579...that 25 years later, is worth perhaps $100-$150 less than what I purchased it new for. (And $579 back then is >$1,000 now.) So figure 66% depreciation! On a quality-made instrument. Just doesn't make sense...except that, perhaps what some touched on: Supply and demand...they started mass-producing instruments in the 70s, early 80s...there likely isn't a huge shortage of my Ibanez or its late 80s counterparts.
But, it is only human-nature to want to spend $300 on a bass (or $1300, etc.) play the heck out of it, give it war scars, and be able to sell it (or my grandkids to inherit an item of value) 40 years from now. Just doesn't seem likely, unless it's Fodera...or the very few in that class (MTD, Pedulla, Thompson, etc.)
That not withstanding, folks truly have touched on some key points (generally) and instruments of interest (specifically); i.e. Squiers, Kubicki, 2008+ Fenders, AMRI Fenders, etc. (And lots of others.) Very interesting, indeed.
Thanks again for the replies and truly excellent reading material here! This thread hasn't gone south, hope it stays that way
Cheers,
Sean
