I currently have 35 guitars and my son has 7. I gave him a choice of my pieces for his HS graduation (within reason) . He chose my '58 Reissue Custom Shop Les Paul. He's become a very good player and his collection is mostly USA made and pretty impressive for an 18 y.o!
My guitar collection is way larger than my handgun collection and by far my biggest passion. I have many Strats, Teles, Tom Anderson, G&L ASAT, Gretsches, 5 PRSs, Taylor, Gibson acoustics, Gibson solid and hollow bodies, Rickenbackers, pre CBS P bass, old Danelectros and my new fav a Duesenberg "Mike Campbell". Most are custom shop, custom made, one-offs, LTD editions and vintage pieces. All have some degree of collectibility. They date from the '50 thru today.
I'm personally not a Les Paul person (not to start a debate, just my preference-but I do love the sound). I typically play a Strat, Anderson, Gibson cs356, SG or a PRS McCarty or Custom 24. On the few acoustic songs we do, I play a Gibson Dove (if we plug into the "house" PA), or a cocobolo Taylor 814ce if amped. And of course the requisite 12 string acoustic (Gibson) on "Hotel California"!
I buy and sell a few here and there, but mostly I just collect. At one time I was up to 48. I think at that point I was a borderline "hoarder" and just flat out was running out of room! I feel my collection is manageable in the 30's. Some, like handguns, are just "case queens" but most see daylite (just not much stage or road time). Others are plucked most everyday.
FYI, I figure I do more than 150 string changes per year! Forget the time on other related tune-ups, scratchy pots, intonations, cleanings, etc. I recently soldered 18 shorted-out guitar cables. I do that at least twice a year. I swap out about a dozen amp tubes per year. Just dusting the stuff is a line item. My hours as my own "roadie" are too frightening to think about.
Yeah, let's save amps and foot pedals discussion for a different day!
