Walrus Audio’s Vanguard puts a new twist on an old idea, with an emphasis on the word “twist.” The old idea is combining two independent phase shifters in one box. But the Vanguard’s tones and features are quite distinct from such analog precedents as the 1970s Mu-Tron Bi-Phase, the rare but revered Lovetone Doppelganger from the ’90s, and MXR’s simple but effective Phase 99.
Instead, Vanguard is an unapologetically digital effect. It doesn’t replicate the cushy, immersive sound of a good analog phaser, but has an edgier modern character. And it offers an array of options you won’t find on most analog phasers, including true stereo operation, remote and expression controls, and fresh-sounding bi-phased colors.
Vanguard runs on any 9V power supply rated at 150 milliamps or higher. As on most modern digital effects, battery power is not an option. The pedal actually houses four phaser circuits. The first one, always active, is a 10-stage phaser with standard rate, depth, and feedback controls. This stage’s output feeds one of three second-stage phasers, selectable via toggle switch. You can choose between a duplicate of the first phaser, a four-stage phaser with pitch modulation, and a six-stage effect with a resonant low-pass filter.
All of which is a long-winded way of saying, “Damn, this thing generates a metric butt-ton of offbeat modulation effects.”
