Dom's kit as to date is as follows:
For recording - Drum Workshop (Maple)
For live - Tama Starclassic Maple
He uses:
Drums
22" x 18" Bass Drum
12" x 8" Rack Tom
14" x 12" Floor Tom
16" x 14" Floor Tom
20" x 14" Gong Bass Drum (used in "Map of The Problematique")
14" x 5" / 14" x 5" Snare drums - various models including Ludwig Black Beauty, Tama Starclassic, Yamaha (not sure about that one) and some others - there's lots lol
Cymbals:
8" A Custom Splash
11" Oriental Trash Splash
14" K Custom Dry Hats (used to use 13" A Custom Projection Hats)
18" Oriental China Trash
18" A Custom Crash / K Dark Crash
19" A Custom Crash / K Dark Crash
20" Oriental Crash of Doom
22" K Custom Ride / 22" K Custom Medium Ride
(He changes his crashes between concerts and in recording.)
He also uses Remo heads on the majority of his drums (exceptions like his Black Beauty which has an Aquarian skin) and Tama Hardware. The sticks he uses tend to vary from time to time but currently it looks like he is using Vater's New Orleans Jazz sticks. He tends to go for a weight which aprox. is 5B...
This is as far as I know really, but if it's wrong I'm sorry - there hasn't really been an official release of his gear for a long time and the majority/all of the above is from observations.
So I hope this helps any of you who wanted to know.
