There's a lot of apples to oranges going in this discussion, which is to be expected.
Generally speaking, IME any instrument does not suck at resale value. There are what should be obvious reasons why some things suck and others don't. The most obvious is demand. If there's little demand top dollar is probably not heading your way. Another is the timeframe in which the sale needs to take place. I've beent he beneficiary of an absolutely ridiculous amount of high end gear that I've picked up so below market it's probably unbelievable. I've probably done that at least ten times this year alone (hint: a bad economy is the seller's enemy and the buyers best friend).
Can bad resale value be avoided? Yes... an informed consumer can easily beat that on average by buying the right way. Close-outs, NOS (new old stock), end of year, impatient or uninformed seller, etc.
I purchased a NOS Alembic Series II (IIRC) bass; like new with case, power supply, etc. from a GC a few years back for $5700 off of retail. Cost me $2200. Now the first thing some folks will think is that's what the bass was worth... and they'd be wrong. That's just what the seller wanted to quickly move the bass for. Lesson: Don't get purchase price and value confused.
I came on TB and offered it up for what I paid for it. Just passing the bass on since I knew I couldn't use it. Zero bites and I can imagine it could've been for the same reason I got my BMW for peanuts: the price was so low people just knew there had to be a catch. In both cases there was no catch... the prices were just ridiculously low. Lesson: despite the edict that if something seems to be too good to be true, it probably isn't... sometimes it is. It's happened dozens of times for me. It just happened again on Monday
Anyway, I returned the Alembic to GC, it turned up on a well known website shortly after at twice what I paid for it and sold immediately. Lesson: I should've just asked for what it was worth
If you don't have to sell, resale doesn't matter all that much. But if you're like most people and have a butt that life can bite you in unexpectedly, it pays to know the market and the worth of your gear should you
need to sell.
The safest bets are lower priced instruments. More than once I've bought basses that were well over $3k less than they had sold for new. Without some real talent, it's tough to lose $3k on a $300 bass.
