I`d love to have a modern sounding phaser with multiple stages, depth and resonance knobs like the Boss PH 2 or a classic sounding phaser like the Bad Stone from Electro Harmonix inside the Helix... The Script Mod Phaser is just too subtle for me... and the Deluxe Phaser is definitely not up to the challenge nor is it comparable to the overall quality of the Helix` modulation effects. I always end up hooking up my Boss PH-3 in the fx loop in order to get those wacky psychedelic tones ready to funk-up the entire world... hahaha. I do not complain about the flangers or the choruses, they sound pretty decent and I was able to the tones I was looking for, for example the intro of Metallica`s "Welcome Home" or some early Van Halen`s with the flangers. I`m down with the Moog phaser as well... Only two phasers is just not enough, specially when considering Helix DSP capabilities.
P.s: I`d like to have the Boss Dimension C as well... hehehe.
