Bought 2001 Ibanez rg570, after 2 years i checked the serial number...
Few years ago, I was a total gear noob. I just wanted a cool-looking guitar and found a listing for a "2001 Ibanez RG570" for $500.
I liked the color, I knew the brand, and the price felt right for a 20-year-old guitar. I bought it, played it casually, and never thought twice about it.
After 2 years of playing, out of boredom, I decided to randomly feed the serial number to google's Gemini model and ask a few questions. The AI tells me: "This serial doesn't match a 2001 model. This is a 1991 Golden Era build from the FujiGen factory.". I called it complete bullsh*t hallucination, but then i checked manually, and GuitarDater reported it as 1991.
After quick check on marketplaces, i found out real resale value - around 1400 usd.
Basically, I accidentally bought a way better guitar than I thought I did, and it plays perfectly to this day.
