Oh hey, Elitist! love that band. You can actually buy their tones. Problem is, you need an AXE FX II. Once you have one, you will never ask for a tone ever again. Agreed, on buying an HD series Line 6 product. If you can get the POD HD Pro, it's your best best to obtaining that sound. You also need to understand Julian runs his own recording studio. His quality is way better than any at home recording artist can probably get. I myself asked this same question a while ago. I really like their guitar tone. But I understand his tone is professional, and well produced. Here's an idea. You can buy his tones for $15. http://www.parallelfocusstudios.com/samples And then see if you can convert (aka, use similar Line 6versions of his settings) the AXE FX settings to Line 6 PODHD PRO. You won't get precise tone, but you will get really close. Check out these comparisons
You can see there are differences. But overall, not too different. I personally like Line 6s better. But that doesn't meant I wouldn't get an Axe FX in a heart beat
