This pedal really changed my thoughts about phaser.
I've been using it so much since I've got it, and I've almost not touched the settings. It sounded amazing straight out the box, but still the knobs can do a whole lot good for your sound.
The Resonance and Depth knobs are great for making your fuzz or distortion pedals work perfectly with the phasing, without making it sound thin or muddy.
One thing that really amazed me is the range of the Rate knob. I never encountered a Phaser that could go so deep and take so long to sweep between the frequencies, but still being able to get that super fast, almost tremolo-ish sweep.
The Vibrato mode is also super cool, but I must be honest and say I don't use it much. I usually just stick to the Phaser setting, because it sounds so great.
I'm honestly a bit baffled on why I don't see this pedal on that many boards. Definitely my favorite phaser of all time.
Would recommend for anyone who loves phaser.
