SD3 is the private collection of Mickey Hart plus my private taiko collection and some of Mickey’s taikos. I had a $15,000 600 lb. drum built for this release. Sometimes I think people are so used to be bullshitted that they don’t realize when something unique comes along. All those drums sampled in East West studio one with 24 microphones. The taikos have multiple mics controllable so you can get the deep low end and definition from the close mics and the big room sound from the room mics. But you still need reverb if you want the sound of ark or HZ. SD3 taikos are really good all around solution. If you really want to play extensive and fast parts it’s very good. Perhaps better than anything. If you just want some big booms perhaps Ark or HZ is better. East West studio one doesn’t have the Abbey Road massive 4 second sound. That video for Ark makes it seem like the Holy grail. It is great. They had a real ensemble in a great studio. Unfortunately, it’s not the holy grail. As a taiko freak for the past 25 years, I can tell you that no one has nailed it yet. Odd because it should be easy. It’s just drums after all.
