I'm looking to upgrade my amp and the two that I have my eye on are these: Line 6 Low Down LD400 Pro and the Fender Rumble 350. Both are at the top of my pricce range. I have played on the Fender at Guitar Center. The other I cannot find in any guitar store here. What's sad is that I live inb the live music capitol of the world but stores here are all chains and most only stock the low end and a little very high end stuff. Nothing in between. Anyway, does anyone have any experience with the Line 6? Of course I will accept any other suggestions. Thanks.
