Both factories use a Plek machine.
Good example. Manufacturers (e.g. Gibson) use PLEK as a marketing tool now, to say it's more expensive and more effort to use the machine, but the result supposed to be superior to the one that can be achieved with 100% human effort.
The Plek machine is a good tool
What it offers is consistency as all guitars will have pretty much the same settings and setup
It also means that the factory can use semi-skilled labour to ensure the guitars are all setup just right rather than needing highly skilled (and expensive) technicians. Thre machine will have been calibrated by someone who is skilled but once the program is in place, the "ordinary staff" can operate it.
It also looks great in the company literature and website etc - impresses potential buyers (and quite rightly so)
With enough cash and enough space I would have one, and a CNC machine and a laser cutter
I would use all three to enhance what I offer - wouldn't diminish anything I do, but would allow me a whole lot of extra options, and free up time once it is all set and running
