EarthQuaker Devices Spatial Delivery V2 Envelope Filter with Sample & Hold

The envelope filter or auto-wah effect is the percussive, vocal effect that revolutionized funk music in the 70's. In 1972 a couple of Guild employees in New Jersey built the very first envelope filter effect, the legendary Mutron III. This tool of dynamic expression was featured on countless records and could be applied to guitar, bass, keyboards and more. When it comes to guitar it's hard to think of a player who utilized this effect more than The Grateful Dead's Jerry Garcia. Naturally this inspired countless attempts at capturing the heart of this circuit but very few have taken it further. That is until the Spatial Delivery by EarthQuaker Devices. 

This voltage controlled envelope filter is capable of nailing the classic auto-wah tones in both upward and downward filter sweep modes. The upward sweep attacks with a quacky vocal quality akin to the chopped up guitar sound of Rufus' Tell Me Something Good. The downward sweep offers the iconic laser-gun sound that Jerry Garcia made famous in the late 70's. If you want to hear our favorite use of this, check out The Dead's "They Loved Each Other" live at Cornell in 1977. Of course the tone shaping abilities of the Range, Resonance and Filter controls let you twist these envelope voices to the extreme, with plenty of opportunity to create entirely new sounds. The really innovative setting on the Spatial Delivery is the Sample and Hold mode. In this setting the voltage controlling the filter is randomized, resulting in a funky barrage of melodic ebbs and flows. The Range knob becomes a rate control in this mode, adjusting the rhythm of sweep for a variety of bouncing, glitchy trails that seamlessly work themselves into musical arrangements. If you've been looking for an auto-wah effect that breaks the mold, sign up for the Spatial Delivery.

The Spatial Delivery is an oddball, a voltage controlled envelope filter that allows you to step outside the universe of funk while reinforcing your secret love affair with auto-wah. It has 3 modes: Up Sweep, Down Sweep and Sample and Hold.

With Range, Resonance and Filter controls you can get super emphasized filter sweeps in the Up and Down modes. The Range, in combination with pick attack, controls the sensitivity and reaction time of the envelope and thus the width of the frequency sweep. The higher the Range and harder the attack equals a faster reaction time and higher frequency sweep and vice versa. Reign in the controls a bit, add your favorite overdrive/fuzz after the Spatial Delivery and you’ve got a real nice resonant, cut-through-the-mix lead tone. Crank the controls back up and you’re a neo-bedroom rock god. In the Sample and Hold mode the filter is controlled by random voltage and the Range controls the speed. Add a sub octave into the mix (before or after) and you’ve just created a deep fried space droid computer freak-out. The filter can be cross faded between high pass (counterclockwise), band pass (center) and low pass (clockwise) for a wide variety of voices. The Resonance control goes from zero to the brink of oscillation and adds more body and ring to the filter voice.

Controls

1. Range: Adjusts the sensitivity of the envelope in Up and Down mode. In Sample and Hold mode, this controls the speed.

2. Mode Toggle: This toggles between Upward Sweep, Downward Sweep or Sample and Hold.

3. Resonance: This is the filter feedback control, it adds more body and ring to the filter voice.

4. Filter: This crossfades between high pass and low pass filters and allows you to get everything in between. High pass is fully counterclockwise, low pass is full clockwise and center is band pass. This is much more useful than a simple switch because it allows you to blend the filters for different sounds!


Suggested Placement

We recommend placing the Spatial Delivery first in your signal chain. However, due to its envelope control, experimenting with pairing and signal chain placement can take the potential of the Spatial Delivery even further.

Flexi-Switch® Technology

This device features Flexi-Switch® Technology! This relay-based, true bypass switching style allows you to simultaneously use momentary and latching style switching.

  • For standard latching operation, tap the footswitch once to activate the effect and then tap again to bypass.

  • For momentary operation, hold the footswitch down for as long as you’d like to use the effect. Once you release the switch the effect will be bypassed.

Since the switching is relay based, it requires power to pass signal.



Power

This device takes a standard 9 volt DC power supply with a 2.1mm negative center barrel. We always recommend pedal-specific, transformer-isolated wall-wart power supplies or multiple isolated-output supplies. Pedals will make extra noise if there is ripple or unclean power. Switching-type power supplies, daisy chains and non-pedal specific power supplies do not filter dirty power as well and let through unwanted noise. DO NOT RUN AT HIGHER VOLTAGES!
