My fave redline tricks:
Use it on vocals with the predelay very apparent, but softened up with some verb and diffusion - sort of a cross between reverb and slapback delay. Very cool sound, to get there see how close you can get the plug to sound like a "delay" first. I think of it as a "soft" delay sound.
I'm not a hard rocker, but this thing makes for some amazing "big stadium guitar stack" sounds. I mean, like huge. Start with the "gymnasium" preset.
And it's killer on toms.
Can't WAIT for the EQ to hit if this is a good example of what you guys are up to!
