So this is my first electric guitar and its a GRG170DX. I bought it this week and I wonder if its normal that guitars sold in shops are 2 years old, since mine was made in 08 in november.
Yes, it's normal.
Don't worry, its fine. Most retailers, especially small ones cant afford to keep buying each years new line to add to their stock.
Yeah, I bought one of mine from a shop in 2008, and it had never been used and was made in 05.
You can even buy vintage guitars which are like 60 years old
Both of my Ibanez's were a year or two old when I bought them. It's perfectly normal, as stock sits on shelves or in waiting in a warehouse.
