I got a new Ibanez GRG170dx guitar from Raj musicals delhi a couple of months back.. I found out the batch number and the stamp, which says the guitar was either made or checked in the year 2001..it has the exact date n even the day sunday writted on it which coincides. But the thing is, this gio series guitars were introduced only in 2004.. How is this possible? The guitar price at raj musicals is also quite cheaper than elsewhere.. Almost 2k less.. the guitar is surely grg170 bcoz all features match.. Plz help!
