When I was into collecting drums I only ever had one set up, but there was a period I had 2 set up. Anyway, while I was still living with my parents rent-free I spent a lot of my money straight up on drums. I haven't seen my stuff much lately (they're stored since I can't play them where I live-- though I might be pitching in on a lockout soon, I might be able to play) but to my memory I have: (these are all player kits, some have mods or modern parts)
12/16/22 RB Gretsch blue sparkle (second favorite kit, I honestly forget if I have the matching 13" tom; previous owner rewrapped and filled holes)
12/14/20 60's Ludwig Champagne Sparkle (orphans brought together, my favorite kit)
13/16/20 60's Ludwig (custom rewrapped walnut veneer, dark stain)
12/14/20 late 60's Yamaha (one might call it light blue onyx)
12/13s/14/17 50's/60's WFL/Ludwig modded 'Imperial Lug Clubdate', Silver Glass
I might be completely forgetting one altogether...
Plus a half-dozen other orphans that I could make up other kits... some weird stuff, 14x14 Leedy, 14x24 70's Ludwig, 14x18 Keller shell kick w/ Ludwig lugs, 12x22 60's Keystone, I think a 12x15 marching snare I made into a floor tom, plus all my snares. I stuck largely to 50's/60's American drums. I also have another half-dozen or more shells or incomplete drums that need something to work.
I don't 'NEED' any of these drums, and they are a pain to move... are there too many? Sure, haha. but they are mine and I love them all. =) That's what's important. If you're not attached to something, get rid of it. I get pretty attached and sentimental over a lot of things so it's pretty rare I sell drums (I have sold some, just not many). Plus most of mine are modded in some way or have replaced parts and I dread the day I have to sell them and explain every little widened hole and rewrap and unoriginal tension rod. =)
