Way back when I was about 17 or 18, almost 20 years ago, my brother's best friend called me oover to come check out this bass he wanted to sell me, he was not a player, he inherited from his uncle who apparantly bought it new and put it away in a closet for years, barely played it.
The bass was a 1958 fender p-bass in absolute mint original condition, tweed case had all the paper work and all the extra goodies, like the curly phone cord still wrapped in plastic bag. Absolutely no wear on the frets, maple fretboard was still glossy and perfect, sunburst with gold pickguard, ashtray covers and original flatwounds. There were a few wear marks on the treble side of the body from the case lining after sitting all those years. he wanted to me for $1000, that was his special price just for me.
Well considering my age at the time and lack of responsibity, I couldn't come up with that kinda cash, he waited a few months, then decided to go have it appraised, then realizing it was worth over 10 times what he originally was asking, he sold it and I lost out.
To this day, I still (even as I write this) get a very queasy sick feeling every time I think about it. Biggest regret ever!
Other than that, I got to play and record on a 66 hofner beatle bass from a friend's studio, biggest, warmest ,deepest sounding bass I've ever played or heard. He also had a few 60s fenders and and really cool old fretless guild that I had the pleasure to record with.
Nowadays I own a 72 p, which I'll take to the grave with me, and a 75 jazz, which was my first "real" bass, sold a 77 gibson g3 that I loved for years, and just last year I bought a really cool gibson bass IV from around 86 that I'm really digging on right now.
