"I’ve seen you use a Klemt Echolette in photos. Is that still your echo, and do you use it live?

Yeah, usually. But we haven’t played live that much yet, so I haven’t used it much in that context. I always use the same two settings: a slapback thing, and a more triggered, triple-echo sound. It also makes for an amazing preamp. You can use any shitty amp with it, and it usually still sounds good. The echo certainly changes the quality of the tone, but if you can use a vintage Fender or an old Marshall, it’s a supreme combination."
