Reducing costs can be done by making the manufacturing process more efficient, which has been happening with increased automation. It does require capital investment, but that's spread across tens or hundreds of thousands of instruments, and you can always sell the decrepit old machinery to Gibson and recoup some of the cost.
If the device is powered from the USB cable and the cable has really teeny tiny cores, and the device takes a fair bit of current, the resistance of the cable might bring the supply voltage down enough for the device not to run.
Sometimes it's because the USB cable is charge only, so you have to be sure to get a data cable.
Also, sometimes it has to be plugged into the PC itself rather than through a hub.
You also need to be sure you've got the drivers installed. If you go into Device Manager you should be able to see if it's connected but the drivers aren't installed.
I can't remember ever hearing about some celebrity buying a high priced collectors instrument (other than occasional mention on Basschat that somebody owns something, generally several years after they've bought it). I also can't see that they would get millions worth of free publicity from that. Could you give an example?
I'm surprised that nobody has mentioned William Shatner yet, for every single one of his covers.
Telly Savalas did a pretty shocking version of "If" too.
I'm just seeing if I can get the vein in @Woodinblack's temple throbbing. And it seems a little arbitrary selecting me to patronise, as the whole of this thread has been opinions. And emojis are for losers.
Your subsequent question was "Why do You think Fender cs would not make Your perfect bass ?" and I answered it. Perhaps it would help if you remembered what you'd said.
That, and Joe Cocker's "Little Help", are very much subjective. Personally, I love both of them. The Alexander Burke version of "Hallelujah" is objectively awful though.
"Hey Mr Plant, my band's just done this cover of Stairway and we were wondering what to call ourselves, here, I'll play it to you <song plays> There, what do you think we should call the band? Hey lads, he said Far Corp. Far Corporation it is then."
I'm not sure how useful this answer is, but the strength of neodymium magnets varies with their size. I see what you're saying, but the magnet material will presumably make a difference as will how they are magnetised. If the issue is relative loudness of strings, I'd suggest experimentation.
I'm looking to do the same thing and I've concluded that it's simplest to cut the DC patch cables that came with the power supply to length and put new plugs on. Cut and shut is another option but wouldn't be as neat.
StageFlex do a 3x1.0 too: https://www.stage-electrics.co.uk/View/21675/stageflex-37027-metre-x-bs6500-h07rn-f-rubber-cable-3core-1mm-black (and in white also).
Given the nature and location of many rehearsal studios, it may partly be a way of holding on to land until someone wants it for residential development and then selling it at a vast profit. For instance, https://goo.gl/maps/xwzpyK6dDXH5DGab9 - on the left is Robanna's studios (also does PA hire and recording, which are further revenue streams), on the right are new apartments which used to be industrial premises the same as Robanna's.
