I was believing they were after reading the US made G&L description :-/
According to http://www.plek.com/en_US/referenzen/produktion/, today Martin owns 6 PLEK pro machines, and G&L only one

I f**** love the playability and the perfect setup of my PLEKed mexican Martin, and I wish I can PLEK my indonesian G&L Tribute S500 as soon as possible (I would gladly have payed an extra 150 bucks for it at purchase time...) but I'm stuck in Thailand without the guitar and the Carvin of my life for I don't know how long ... (can't have it all at the same time

Here's the world map of PLEK machines used for service or production you are in a similar case (in need for the best possible setup): http://www.plek.com/uploads/plek_worldm ... hp?lang=en
Note that PLEK machines does require a skilled operator (preferably a luthier with good practice in neck, frets, bridge and nut setup).
