i think he does session work alot. he used to do those drum seminars with Peavey Radial Pro sets (which were amazing) but now Peavey don't make the Radial sets.. amazingly he does not endorse other drums. He stills uses the old Peavy's . Just shows how honest the guy is. He plays drums he likes and not what people pay him to say he likes. I think he worked with Bruce Kulick recently.
those Peavy drums are not my thing, but if you want POWER, those things are top of the list. You can pick them up cheap and you will have the ultimate in Rock Power. Way ahead of their time. For me too much and too over the top look wise.
