One of Electro-Harmonix’s most popular effects, there are many reasons to love the POG2. One major reason is 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. Lying on the effect more heavily creates dramatic swells perfect for shaping gently shifting ambient soundscapes and synth-style pads.

Key Features

  • Compact Pico chassis
  • Attack Envelope effect of the EHX POG2
  • Polyphonic attack envelope applies swell to each individual note played

Controls

  • VOL – adjusts overall output volume
  • ATTACK – adjusts ATTACK Envelope Time
  • FILTER – button engages LPF and selects resonance settings
  • FREQ – sets cutoff frequency of LPF

MOD controls depth and direction of filter modulation Power adapter included

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-favourite effect, now in its very own pedal.

Guitar Effects Pedals is a useful category for players looking to shape their guitar or bass sound in a more focused way. Products in this area can help with tone, control, routing, performance or creative sound design depending on the exact type of gear involved.

For anyone building a pedalboard, guitar effects pedals options can help fill a specific gap in the signal chain or open up new sounds that are difficult to achieve with an amp alone. They are worth exploring when you want a more personal, flexible and practical setup.
