My favorite guitar is the first one I ever got and I still use frequently, a MIM Fender Standard Stratocaster. It has been through numerous hardware changes throughout the years, including a neck swap to get jumbo frets. It was made in 2000/2001 which is when I got it. It's actually funny, well to me anyway, I have owned and sold off a ton of guitars over the years that were much nicer looking, better wood/build quality, some costing 4x as much, yet I have kept my Strat and always considered it my main guitar. It's what I learned to play on, been through a lot with it haha. My other favorite is the Gibson Faded Explorer I got a couple years back, if it weren't for my Strat it would be my #1.
