Besides the Slingerland Artist, or "Old Number One", as he called it, Neil had some Ludwig 3x13 piccolos on his left side during the "Roll The Bones" and "Counterparts" years. He also had a brief stint using Solid steambent snares. He claimed to have "retired" Old Number One when he moved to DW. I suspect that snare's still in storage somewhere. If it ever went on sale, it'd fetch about a bajillion bucks.I think NP kept that snare with the original copper wrap on it until he got the Artstar prototypes (the red kit). At that point he nervously had it refinished in red. Then again with the Ludwigs and their color changes. I don't know how much he used it on Presto, but I think around that time he started mixing in Craviotto piccolos and others until he decided he wasn't feeling the Slingerland anymore.
That snare was always hit and miss, IMO. It sounded best on Permanent Waves followed by Moving Pictures. There's a lot of recordings where it sounded kinda mushy.
I like his VLT but I suspect it's had a more than average amount of treatment put to it. I've never played a DW snare that sounded like the Snakes and Arrows Snare sound, for example.
