No, precautionary is knowing WHO made your instrument. Look at Gibsons. You can't touch a new paul for less than 2Gs and in my opinion, for the money, they are junk.
When buying a custom you are paying for the priveledge of having a guitar built by one person who will attend to your guitar from the raw lumber stage all the way through the final setup. With a manufacturer, probably 100 people have touched your guitar and as many machines. CNCs, robo buffers, assembly line fret installations and dressing, caked on plastic finish..
I understand where you are coming from but if you can find a store that sells some custom instruments go check them out. I'm willing to bet you'll do a complete 180. At this point in my life, I will bever buy a big name guitar again.. at least from the big 2
You'll find too a lot of builders are willing to throw limited lifetime warrantees in there. You won't get that kind of guarantee OR service from one of the biggies.
The KxK guitars are totally not my style.. but I can tell from looking at them that they are well made. Nice details, and some of those in-stock models.. 1199 for a custom V with a road case.. that's a steal if you ask me. Go drop 1199 with a big company and you're likely to get one of their "import" models.
