thanks for your replies guys yes well mine was made in february 2011 and yes its chambered and it has all these changes and special modern thing on the guitar mine is a lightburst ,i used to have a studio,standard,classic antique but sold them all due to money.Now i had a great opportunity 6 months ago to buy that guitar a guy who had a guitarshop sold his demoguitar so that guitar was just a demoguitar in perfect condition and it was and had it for a very good price which means around 1200 US Dollars.So i grabbed it,i used to have the same guitar a year or two but since i got divorced i needed money so i sold it and happy i get that guitar back.
