Creating Double Track Guitars from Mono Recording in Reaper
In this video, i used the Voxengo PHA-979 plugin
for 90 degree phase shifting, and Guitar Amp plugins from Bogren Digital.
To get different, but well-matched sounds on two channels, the selection of guitar amps must be very careful,
so that they don't act negatively on each other. It seems to me that the choice of amplifiers in the video is successful.
P.S.
A 90 degree phase shifting helps tracks sound clear without issues like out-of-phase, or sounding like a phaser effect.
