First off, to expect any string instrument hanging on a wall of a store to be in tune in just silly. Seriously. I mean come on.
And I have never picked up any bass and could not tell if I liked it or not because of the string height was not where I prefer. Meaningless when grabbing a bass of the wall to check it out.
Who cares if the strings are higher than you like? Does not effect the tone or the feel of the neck.
Do people bash box stores as a hobby?
1. expecting something to be perfectly in tune is unreasonable, yes....expecting it to be somewhere in the correct octave isn’t
2. again there is difference between action being higher than one would prefer and being so high it interferes with playability.
3. I have always purchased instruments from smaller local shops in the past ( granted 15 plus years ago), but those are few and far between these days. My prior experience shopping for instruments lead me to expect that things on the showroom floor should be at least gone over....these instruments were the equivalent of (analogizing to my other hobby) teenagers assembling bicycles at Target with crescent wrenches and hammers. Now to be fair, not ALL the stock I tried were unplayable.....the stuff on the upper racks was quite better. Now perhaps I am out of touch with modern commercial realities....fair enough. But i have no particular axe to grind.
