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.

  • Ambient textures, dynamic swells, and tone shaping

Always order big!
I needed a minimum of 2 AWG wire to create interconnects between batteries in a large bank. If you note, these say 1/0 Gauge, not AWG. What is 1/0 Gauge? Who knows, it's fake. Meaningless, because it is not standardized so you have no clue what you are getting. What did I get for my 1/0 Gauge wire? Something that was in between 1 and 2 AWG (closer to 1). This was perfect for my needs because I knew darn well how big to order when they say gauge instead of AWG. As a rule of thumb: If they as gauge, order 3 - 4 sizes larger than you need in AWG. This will always net you larger wire than you need but I have never had it net me wire smaller than I needed. At the price I got it for during prime days, it was a steal for 2 AWG wire, so I win! I hope you found this helpful!

Heavy duty and has lasted three years so far
I have had this relay installed in the engine bay of my Lexus RX 300, functioning to link the front battery to the additional battery in the trunk whenever the ignition is on. The relay has worked reliably for about three years now with no complaints besides one minor comment, be careful when threading down the nut on the Low voltage side. It is prone to stripping
