Is there any halfway decent way to mimic a 12 string sound via anything but a modeling amp etc. My band is working on some new stuff that seems suited to that kind of sound, but I don't want to shell out the big bucks for top shelf gear, until I know for sure that it's right for the songs. I'm always looking for an excuse to try new pedals. :D

Any thoughts?

But he's playing awful.

try en effect that's called pedalpitch, simply give your guitar the "raw" sound and the octave. or set it to the same tune, so you would have it twice (well, there's different kinds of 12 strings, chorus like, octave, completely different tune such as 3 half tones up/down...)

maybe some chorus also
