To make this basic as I can. Here ya go...
1. No big secert, Roger used the DX-100 and the patch was the Hard Brass.
2. Roger had a custom made one just like Teddy has a custom made one.
3. The closest your going to get to that sound is having to buy a Heil or Banshee.
4. Hours upon hours upon hours of teeth chattering, mouth moving practice.
Believe me, don't get into it if your not serious. It takes a lot a grueling time. It took me 3 years to get it somewhat down and even now I'm still learning tricks.
oh yeah, when Roger did his records he stacked the harmonies like a singer. It could be 8 to 16 trks a note. That's how he got it to sound so thick and good. And of course he is a great player as well. That really helps. Teddy is unbelieveable on the keyz as well.
Hope This Helps....I love to see the future do what the past hasn't yet. I hate holding secerts.
