“I’m very, very excited about this amp,” he says. “Ashdown and I have been talking about doing something like this for years. It all started back in 2006, on a David Gilmour tour, when I had WEM logos put on my Ashdown cabs. We always had this joke about old WEM cabinets, because in the early days, it was all WEM gear and PA equipment.”
