Very good doubler by TC Electronic, but be careful!!!
Regardless of what the manual says, it only works correctly if it is placed first in the guitar and then in two guitar amplifiers (L/R) or in the stereo input (if available) of a Guitar Modeller (line 6 Helix, Axe-FX, etc.) or in two separate G.Modellers, one for L and one for R.
If placed after a distortion pedal or after an IR cab simulator, or in the output of a line 6 pod for example, you will have an effect like a phaser!!! completely useless, and no relation to a doubler.
