TC Electronic Crescendo Auto Swell Pedal New | Pre-Order (ETA: 2/25/2026)

Every once in a while an effect arrives ahead of its own time, and before guitarists can figure out what do with it, it’s no longer available. As a result, they become extremely valuable because of their rarity. CRESCENDO AUTO SWELL brings one of those iconic and rare effects back to life, and makes it readily available, affordable and built to withstand a lifetime of abuse.

A Rare Bird

Just like the musical term, crescendo means to start at a low volume and then swell to a much louder level, which is similar the sound of a violin being bowed. Now you get those sweeping swells from your guitar, without searching high and low for hard-to-find vintage gear, and we’re talkin’ about a brand new, in the box CRESCENDO AUTO SWELL pedal that is backed by one of the most generous programs. Try to get that at a garage sale!

Subtle and Simple

Thanks to just 2 knobs (Sensitivity & Attack) and a true bypass switch, CRESCENDO AUTO SWELL is easy to use and functions much like a noise gate, only in reverse. Instead of clamping down on the tail of your signal, CRESCENDO AUTO SWELL mutes the initial attack and then swells up to full volume. Put simply, it removes the pick attack and blooms into a beautiful swelling note.

Roadworthy

Housed in a sturdy metal enclosure, CRESCENDO AUTO SWELL was built to withstand years of daily abuse. The high-quality analog circuitry and true bypass switch respects your tone and keeps the signal nice and clean. So whether you’re creating pedal steel like chord tones, the sound of foghorns cutting through the fog, or the sweet swelling strains of a violin section – CRESCENDO AUTO SWELL was made just for you!
