I've often wondered myself how to get that "double-tracked" sound live.
I think Robert S mentioned that he was able to do it or at least get close with a stereo rig and a pitch shifter set to delay one side by a few milliseconds.
Well I won't be able to EXACTLY recreate the tone but something just seems to be missing when my band was practicing recently. Softer and clean parts were ok but the heavier distorted parts seemed to lack a little. I don't really know how to describe it.
Tone was great but...
So you record an album with tons and tons and tons of layered guitar tracks. How do you do it live?
Compressor pedal?
Octave pedal?
Hire some guitar players?
2 amps at once?
Samples with a loop pedal?
Leave it up to the sound guy?
