The TC Electronic Vortex is a compact digital flanger pedal that runs from a 9V battery or DC adaptor1. It offers two types of flanging: a basic flanger and a tape flanging emulation, also known as through-zero flanging, selected by a toggle switch1. Guitar World's launch coverage described its range bluntly: "This flanger goes from classic flanger sounds to a 747 taking off!"2
The Vortex arrived as part of a new range of simple stompboxes from TC Electronic, launched as the opposite of the company's more complex Nova series, which used scrolling memories, double footswitches and 12V power1. Alongside the two flange modes it carries TC's TonePrint option, which includes prints from Orianthi and Bumblefoot3.
What the Vortex does: classic and tape flanging
The mini-toggle switch moves between your typical flanger sound and Tape mode, which recreates 60s tape-flange effects2. The basic flanger covers the familiar jet-plane sweep players know from the effect's stompbox history, while the tape setting reaches sounds a conventional pedal flanger cannot.
MusicRadar's reviewer Trevor Curwen found the tape option the more interesting of the two1:
"It's the tape option, though, that's perhaps more interesting in dishing up less common sounds, especially so when phase cancellation occurs at the zero point"1
That zero point is what through-zero flanging means: the modulated delay briefly matches the dry signal's timing, so the two signals cancel rather than sweep past each other, the way two tape machines drifting in and out of sync did in the 60s. Pedal of the Day's reviewer summed up the range as "shallow and subtle to peaking and tremendous," covering all flanging needs52.
The controls
Four knobs control speed, depth, feedback and delay time1, plus a three-way switch with selectable effects variations, including a TonePrint position1.
| Control | What it does |
|---|---|
| Speed | Controls the pace of the modulated signal, from a subtle chug to a fast, whipping whirl5 |
| Depth | Mixes in more and more of the flanged signal with your dry guitar signal the more you turn it up5 |
| Feedback | Creates wacky signal-crossing patterns and noises, from a slight echo to a crazy self-oscillation-type modulation5 |
| Delay Time | Sets the base delay around which the modulation sweeps1 |
| Three-way switch | Selects between effects variations, including a TonePrint position1 |
| Toggle switch | Selects between the typical flanger sound and Tape mode5 |
Premier Guitar's reviewer found the control set approachable: "With controls for Speed, Feedback, Depth, and Delay Time, the Vortex is easy enough to navigate"3.
Bypass, buffer and dry kill switches
Inside the pedal, DIP switches handle two jobs that matter to how you place it on a board. One selects a high quality buffer rather than the default true bypass switching mode, which MusicRadar's reviewer notes is useful if the pedal sits at the start or end of a long chain1. The second offers dry kill for effect only, for when the pedal is used in an amp's FX loop1.
If you run the Vortex in an amp's effects loop, flip the internal dry kill DIP switch so only the effect signal passes. In front of the amp, leave the dry signal in place and the default true bypass keeps your tone untouched when the pedal is off.
Power: 9V battery or DC adaptor
The Vortex is a compact digital pedal that runs from a 9V battery or a DC adaptor1. Battery access is by removing the pedal baseplate via a large chromed knurled screw that needs a coin or screwdriver to undo1, so a battery swap is a bench job rather than something you do mid-gig.
TonePrint
TonePrint is TC Electronic's system for loading new presets into the pedal, and on the Vortex you can upload new sounds right from your smartphone5. The TonePrint option includes prints from Orianthi and Bumblefoot, and Premier Guitar's reviewer felt that addition, together with the Tape flange switch, really expands the pedal's range of voices3.
The Vortex and the Vortex Mini
TC Electronic later scaled the Vortex down into the Vortex Mini, a mini flanger announced in 2014 as one of four miniaturized versions of the company's pedals7. The Mini is built with the same enclosures as the company's PolyTune Mini, Ditto Looper and others8, and its controls are reduced to speed, depth and feedback9.
The Mini keeps TonePrint support, allowing wireless beaming of new presets via an iOS/Android app and tweaking sounds with the PC-based TonePrint editor over USB10. It also adds true bypass plus Analog-Dry-Through, which maintains the full integrity of an analog dry signal path even when the flange effect is engaged11. MusicRadar's reviewer Mike Astley-Brown highlighted its feedback dial: "take it out for Andy Summers-style chorus tones, or turn it up for EVH whoosh"10.
What reviewers said
MusicRadar's verdict on the full-size Vortex was straightforward:
"This is an excellent pedal, and is sensibly priced."1
The same review called it very good value even without TonePrint, which sets it apart from the herd1. Pedal of the Day's reviewer called the pedal "a lot of fun" and praised the Feedback knob in particular for the wacky signal-crossing patterns and noises it produces, from a slight echo to a crazy self-oscillation-type modulation5. Premier Guitar offered one caveat common to the whole effect type: "The Vortex Flanger, like any flanger, is not an effect for everyone"3.

Questions
Is the TC Electronic Vortex true bypass?
Yes. The Vortex defaults to true bypass switching, but an internal DIP switch lets you select a high quality buffer instead. MusicRadar's reviewer notes the buffer option is useful if the pedal sits at the start or end of a long chain, where true bypass alone can cost you high end through cable capacitance.
How do you change the battery in the TC Electronic Vortex?
The 9V battery is reached by removing the pedal's baseplate. It is held by a large chromed knurled screw that needs a coin or screwdriver to undo, so no special tools are required, but you will want something handy in your pocket or gig bag when the battery runs down.
What is TonePrint on the Vortex Flanger?
TonePrint is TC Electronic's system for loading artist-designed presets into the pedal. On the Vortex you can upload new sounds right from your smartphone, and the TonePrint option includes prints from Orianthi and Bumblefoot. The three-way switch has a dedicated TonePrint position alongside the two flange modes.
Can the Vortex Flanger go in an amp's effects loop?
Yes. An internal DIP switch offers a dry kill option that removes the dry signal and leaves effect only, which is what you want when the pedal is used in an amp's FX loop rather than in front of the amp with your guitar.
Does the Vortex do through-zero flanging?
Yes. Alongside the basic flanger, the Vortex offers a tape flanging emulation, also known as through-zero flanging, selected by a toggle switch. MusicRadar's reviewer found the tape mode dishes up less common sounds, with phase cancellation at the zero point creating strange tremolo-style effects.
What is the difference between the Vortex and the Vortex Mini?
The full-size Vortex has four knobs (speed, depth, feedback and delay time), a three-way mode switch and internal DIP switches. The Vortex Mini is a smaller digital flanger with three knobs (speed, depth and feedback) in the same enclosure as TC's PolyTune Mini and Ditto Looper, with true bypass plus Analog-Dry-Through and TonePrint support.
