These 2 things are not mutual exclusive though. You absolutely can use a PCB to lower costs AND maintain high quality if you design the PCB well and populate it with high quality components.
Bogner has been using these pots on Flagship amps like the XTC and it's not an issue at all.
Conversely, you can also have something like this:
That's a $500 plexi clone from China. A handwired piece of shit loaded with the cheapest possible components.
Guaranteed that the Bogner is a better amp AND more expensive to make.
