I've got a problem... I admit it.... I am a packrat.
I've got more "vintage" stuff than anyone should have. My original Guild S100 and Guild Thunderbird amp from the late 60s- early 70s. Two Yamaha AW recorders, Roland RP355, PodXT, Peavey Transformer 112 amp, National (Valco) amp, original Peavey Classic 30.
There's the turntable I bought while in high school and the Sony receiver and Marantz speakers from about '73, a Sony 650 tape deck, a dead Dokorder 8140. Lots of computers... Apple ][+, TI 99/4a (a few), various Atari computers and at least 6 old PCs (Win 95/98 or Win 2000 upgraded from DOS). Full stereo system from about 1980. If 10baseT networking ever gets popular again, I've got plenty of cable and some cards, plus copies of Novell Netware and Novell DOS. The list goes on. Computer software (original Doom, SSI wargames, Myst, LodeRunner, Infocom games, Kings Quest, Scott Adam Adventures)
Some of the things get occasional use. I played my S100 into the National just the other night. I updated the AW16G to an SD card a couple of months ago to play with. I upgraded a computer with Win XP so I could play Diablo and Age of Empires and a few other old games.
But so much of that stuff is sitting in the basement and hasn't been fired up in over 5 years. I keep thinking some day I'll pull out something and fire it up.
For recording I find that a DAW with a USB interface is infinitely easier and faster to use than anything I had before. If I had to use PCIE cards or DATs, I probably wouldn't even be doing any recording. I pretty much gave up on tape over 30 years ago.
What gets used is reasonably recent. The R24 and 16x08 with the Lenovo desktop and Reaper, various guitars and my AmpShop 65 Princeton, DSL401 and Strymon Iridium. Wednesday I'll pack up my PA (Carvin PM15s, QSC 2450, Yamaha MX12/4) and the Princeton, couple of guitars, mics, stands and cables for a trip to Michigan. It is a mix of old and new. But if something breaks, it will be replaced with up to date gear. My pedal board is mostly recent except for the Vox Wah and Visual Sound Liquid Chorus.
My buying of new gear has slowed in recent years. I bought one guitar in the past 8 years, a few pedals and some mics. I considered buying a Tascam Model 24, but the situations where I would likely use it are getting fewer and fewer. Spending $1200 on something I'll probably use 2 or 3 times isn't practical. If I was 20 years younger, it would be a no brainer.
If my great nephew ever gets to the point that he's joining a band, he's going to get plenty of free gear!!!
