Bill feels at home tech-ing for David, and rates him as a player.

“David has a great sense of humour and he's a fantastic player. I started with David in 2004, off and on with another keyboard tech (I would come in if he couldn't make a show). I really enjoy working with these guys. It's a great outfit and everyone has a really great attitude.”

What's the process for setting up the keyboard sounds for a new album when the band take it out on tour?

“After the band are done with a record, I'll go to Jon [Bon Jovi]'s studio with Mike Rew and we'll take all the keyboard parts that David has recorded and pull them out by themselves so that I can hear them clearly. I note all of those sounds and then I get to the synthesizers and start finding sounds that are close to them, if not the exact sounds.

“After that, I start constructing the sounds for each of the songs. David will then come in and go over the sounds with me as well, because he will have heard the record from a different perspective: I've heard it technically, he's heard it more creatively. David knows what he wants, which makes him a pleasure to work with, so it usually takes us around half a day to perfect those sounds.”
