I don't buy guitars often (anymore) but I've owned a lot of them over the years and still have all the good ones I ever had, the ones I didn't care about I sold.
I still have the first good guitar I ever owned, '74 Strat, I'm the original owner. The Tele I bought last year was the first guitar I bought in 20 years, although my wife bought me a 50th anniversary special edition Fender Strat for my birthday back in 2004 because I also turned 50 that year. Great wife!
In truth all I need is one guitar, but I love them all and they all mean something to me. I play them all too, I don't believe in wall hangers.
