I bought another pedal that incorporates a swell effect, so I no longer need this excellent compact swell pedal from EHX. The primary effect is derived from the POG2's attack envelope, applying an attack envelope to each note played (single notes or chords) and adding a modulated low-pass filter.

I’ve used this pedal gently and it’s in mint condition. I’ll pack it carefully before sending it to you in the original box with all of its original contents, including a still-wrapped power supply that I never opened. 

More details below. Let me know if you have any questions, thanks!

Core Effect

• Polyphonic attack envelope applies swell to each individual note in a chord or line
• Adjustable from quick, subtle attack shaping to long, slow swells

Controls

• ATTACK — sets attack envelope time
• VOL — overall output level
• FREQ — cutoff frequency of the low-pass filter
• MOD — depth and direction (up/down sweep) of filter modulation
• FILTER button — engages LPF and selects resonance setting (low/high)

Other

• LPF modulation timing is linked to the ATTACK knob setting
• Compact Pico-format chassis
• Power adapter included
