I think both posts are absolutely true.
Man will never be as accurate as a CNC machine but then the machine won't go searching through the wood store for the best peice of timber.
I totally agree that once a bass or guitar gets to a certain standard (or cost), say £600 or £700, there's going to be very little more that could be done to make it tangibly better.
The only reference/experience I have is with Overwaters, I own 2 Perception Deluxes which are circa £2300 new and very fine instruments indeed, i also have an Aspiration Elite ( one of the tanglewood S Korean jobs) and there is very very little difference in either build quality, finish or tone.
But for sure, the thrill of ordering a custom build is way greater than walking into a shop and asking for "that one", but how much more is that thrill worth?
And what about snob value, if we're honest, there's a bit of that involved too?
