Maybe 6 or so years ago when my wife and I were still teaching after-school guitar classes, a colleague of hers retired and gave us his classroom full of guitars.
On top of the 25 or so Fender acoustics we already had, we received maybe 5-6 Squire and other cheap Strats, a Taylor electric, 4 Squire P Basses, a truckload of combo (including that AC15 I had) and keyboard amps, a few keyboards, a cheaper Gretch drum kit with cymbals and a few boxes of strings. Oh an a couple more acoustic guitars, like three multi-stands and a box of percussion instruments. Oh yeah and a box of shirts and straps. Probably some more stuff, but I've sold off most of the amps that didn't completely fall apart and a few of the cheaper electrics.
I keep guitars in every room. I have my AZ, my S2, a Strat, a 7 string, an 8 string, Bass, and a travel guitar in the master, my son has a few guitars and a bass in his room. 3 guitars and 2 Basses in the living room, a guitar in my daughter's room.
Oh and violins! We have a few violins and violas. My oldest daughter has those in her room because she wants to learn.
I haven't really gotten to the drums yet either.
