Enhancer block with give some stereo width to your track, but can never replace a TRUE double tracked guitar sound (Esp for metal rhythm tracks). Enhancer are good for playing live when you dont have two guitarists in your band.
I would rather prefer this then an enhancer block:
> Split my signal into two path, pan one right and one left (75-100%)
> Use a different amp/cab combination for the second path.
> Add a delay before the amp,
> Mix only wet signal, level 100%
> Only 1 feedback,
> And add a modifier to your "Delay time" parameter to modulate between 7 ms to 18 ms (depends upon your preference).
> Also if you could modulate the volume of this path by 2-5%, that would be even better
This will give you a better dual guitar sound when playing live.
