The Electro-Harmonix Pico Swello is a groundbreaking compact effects pedal designed to deliver rich, polyphonic volume swells and reverse effects with unmatched precision. Drawing inspiration from the renowned POG2 Polyphonic Octave Generator, the Swello automatically applies a smooth, natural volume envelope to each note—no need to tweak sensitivity or alter your playing technique. Perfect for guitarists seeking ambient textures, cinematic swells, or dynamic tone shaping, this pedal redefines expressive performance.

Beyond volume shaping, the Swello features a responsive low-pass filter with two adjustable resonance modes, allowing players to sculpt tone depth and harmonic complexity. The filter’s cutoff frequency can be modulated by the attack envelope, unlocking lush, polyphonic envelope filter effects that respond musically to every note. With intuitive controls including VOL, ATTACK, FREQ, and MOD, the Swello offers total control over output, envelope timing, and filter sweep direction for both upward and downward modulation.

Built with a buffered analog bypass, the Swello ensures clean signal integrity when disengaged and pristine tonal clarity when active. Its compact chassis, 9 V DC power operation, and rugged construction make it equally suited for studio production and live performances. Whether you’re exploring ethereal ambient layers, reverse-style swells, or expressive filter movements, the Electro-Harmonix Swello delivers professional-grade tone shaping in a versatile, pedalboard-friendly design.

  • Digital attack envelope effect from the POG2
  • Ambient textures, dynamic swells, and tone shaping
  • VOL, ATTACK, FREQ, FILTER, and MOD controls

Nice upgrade 51mm for me
Color: Silver
This is my second 51mm machine. I never used the included handle or basket… I kept my existing HUGH IMS precision basket and bottomless portafilter. The temp and preinfusion are set and not adjustable but fine (reduced variables). I defeated the shut off by volume by setting higher than needed (wish that was easier to turn off). I like to manually shut off when I hit 30g on my scale. The machine will drip since there is not solenoid valve so I just pull the scale from the try when mouse tail breaks and drip starts. The steam wand and hot water dispenser is a massive upgrade (from Capresso EC50) and the real reason for my upgrade. I would have paid $50-100 more for the improvements listed… but I guess most people would not so this is about the best option for me with 51mm (keeping all the 51mm three lug portafilter stuff I own). 5 stars = for me and the price
