Pico Swello
Standalone version of the POG2’s unique Attack Effect
One of Electro-Harmonix’s most popular effects, there are many reasons to love the POG2. One major reason being its unique attack filter, applying attack envelopes to each individual note played whether in single notes or in a chord. This creates a very musical, multi-voice effect that’s extremely adaptive to any musical style. This polyphonic attack filter is the core of the PICO Swello generating polyphonic and reverse sounds with the addition of a modulated low-pass filter for even more expressive tones.
Implemented subtly, the Swello adjusts your guitar’s attack to sound smooth and flowing even while playing fast lines and arpeggios. Laying on the effect more heavily creates dramatic swells perfect for shaping gently shifting ambient soundscapes and synth style pads.
The simple 4-knob control layout is easy to drive starting with the heart of the pedal, the ATTACK knob. Turn up ATTACK to go from a quick, gentle attack time to slow, long swells. VOL controls the overall output and is useful for making up for the perceived low volume of long attack effects. The rest of the controls apply to the Low-Pass Filter. The Filter Button engages the LPF with adjustable low and high resonance settings. The FREQ control adjusts the cutoff frequency of the LPF. The MOD knob controls the depth and direction of the LPF envelope for upward or downward filter sweeps over a narrow or wide range of frequencies limited by the cutoff frequency. The LPF’s modulation timing is tied directly to the ATTACK knob setting. Combining the LPF with the Attack Envelope brings added musicality and expressiveness to fan-favorite effect, now in its very own pedal.
Controls:
1. VOL - Adjusts the output volume.
2. ATTACK - Controls the attack envelope time. As the ATTACK knob is turned clockwise, the attack time increases producing a slower swell, reverse effect, or filter sweep.
3. FREQ - Controls the cutoff frequency of the low-pass filter when it is active—LED set to orange or red modes. If filter modulation is enabled via the MOD knob, FREQ sets the maximum frequency of the filter. The filter is fully disabled when the LED is set to green.
4. MOD - Controls the depth and direction of the filter envelope. The timing of the envelope filter modulation is directly tied to the ATTACK knob. Filter modulation is disabled when MOD is at the center (noon) position or when the filter is off.
5. FILTER Button - Enables the low-pass filter and chooses the filter resonance setting:
*NOTE: These resonance settings can be changed, see the section Resonance Adjustment.
Resonance Adjustment
By default, the filter resonance, or Q, is set low for orange mode and high for red mode. Each mode may be adjusted independently to suit your taste, allowing for two resonance presets:
1. Press and hold the FILTER button.
2. After two seconds, the LED blinks.
3. Release the button—Resonance Adjustment mode is now active.
4. The VOL knob controls the resonance setting for orange mode while the ATTACK knob controls the resonance setting for red mode.
5. You may still press the FILTER button to switch between filter modes, and the FREQ and MOD knobs work as usual.
6. When you’re finished making your resonance adjustments, exit Resonance Adjustment mode with another press and hold of the FILTER button for two seconds, until the LED stops blinking.
