"I'm very luddite with my equipment, advances in technology, MIDI and stuff. I've just been persuaded to use a DEP-5. I haven't actually opened the manual yet, though I have found a really good backwards echo. Everything else I use is Boss pedals in one of those little carrying cases, and I swap them about depending on what I want. And a Cry Baby wah wah I've had since the group's inception. I've been told it's become a very fashionable guitar accessory again — I keep reading about new designs of wab wah. It's like when you buy a car you always see your make on the road."
