Voltage-controlled envelope filter pedals seem to be en vogue again. This time, though, they’re not just for neo-funkateers. Yeah, it can be tough to plug into one and not go all P-Funk. But wily guitarists have demonstrated that when you mate resonant filters with fuzzes and other modern noisemakers, it’s possible to move well beyond the usual clean-toned quackety-quack.
But really, most of today’s envelope filters aren’t that far removed from Mike Beigel’s 1972 Mu-Tron III, the first voltage-triggered filter effect. Nowadays you can choose from many Mu-Tron clones and spin-offs, including models from Beigel’s own Mu-FX line. Given that, it’s the little twists and variations that make a modern auto-filter compelling. And compelling is certainly the word for the new Spatial Delivery envelope filter from Earthquaker Devices.
The Spatial Delivery layout seems simple. There are only three knobs: range (sensitivity), resonance (feedback), and filter (the cutoff frequency). There’s also a small toggle with three settings (up, down, and sample and hold). The effect lives in a standard 125B-sized enclosure with top-mounted plastic jacks and a silent relay switch. Old-school through-hole components populate the tidy circuit board. Spatial Delivery runs on standard 9V power. There’s no battery option.
