Four Flashback delays combine into a new day for delay.
Flashback Delay, the sounds, the vibe, TonePrints, the entire package - it was a smash hit that rocked the world. But TC is more about moving things forward and listening to the feedback from the guitar community. And so, when wishes for things like presets and tap-tempo started rolling in, they listened.
Delay Done Right
Think of your favorite delay sounds and chances are it's a TC sound. TC's 2290 Dynamic Digital Delay is one of the most coveted pieces of gear out there today. They made sure Flashback X4 delivers the legendary TC quality at every turn. From the awesome digital 2290 sounds to beautiful analog tape echoes and more exotic vibes of a reverse delay, Flashback X4 delivers every delay sound under the sun - past, present and future.
So many guitarists out there wanted presets, and the ability to switch between delay sounds instantly. Using Flashback's amazing sounds but switching between flavors made sense, so Flashback X4 caters to that wish perfectly with three presets that can be as different and varied as you need them to be.
Creativity In Your Own Tempo
The tap tempo feature was a no-brainer as that is already a fan favorite with some of our other delay pedals. You can easily set delay times or sync up with for example a drummer. Match delays to your guitar rhythms or solo ideas and diversify your playing with different tempos.
No Time Wasted - Plug And Go!
One of life’s nice little surprises is that Flashback X4 comes with a 9 V DC power supply included, so you dont have to waste any time and can get straight to rocking.
Express Yourself
Flashback X4s total dedication to delay shines brightly in the expression pedal input. Many guitarists dream to have direct control over delay parameters and Flashback X4 gives you exactly that. But it’s just not one parameter you can control, you can choose to control either the delay time, the feedback or the delay level of your sounds, giving you unprecedented control (and a good reason to pretend you are Steve Morse).
USB / Beam
Yep - there’s a USB port. But it’s not for boring stuff, we’ve got some features in store that we want to put out once we’ve perfected them or once music is ready. And those updates would be free. You can also load TonePrints via the USB, but all the hip kids are doing it via the TonePrint app on their smartphone. It works wirelessly and flawlessly and it’s also totally free.
I/O Stealing The Show
Flashback X4 allows for MIDI clock sync - perfecting delay times to your exact wishes. You can change presets and control X4 externally, for example if you wanna have it in a rack or safely in your backline.
X4 Gives Great Headroom
From guitar- to amp effect loop signals, Flashback X4 handles anything you throw at it with ease.
Creativity In Your Own Tempo
Instantly synch up your delays with your band’s tempo, the ideas in your head or whatever else is guiding you without taking your hands of the guitar or bending over the pedal. Simply tap the tempo with your foot and get on with things!
Maximum Signal Integrity
Flashback X4 goes with the flow like other TonePrint enabled pedals. Whatever your set-up or situation, Flashback X4 can adapt and guarantee optimal signal integrity - via small dip switches, Flashback X4 can be set to either True Bypass or Buffered Bypass.
The World At Your Feet
A much requested feature from the original Flashback Delay: presets. here they are, three presets at your disposal but now the questions becomes: how to divide your time between three great accesible sounds?!
Separated At Birth
In Flashback X4, the delay engine is completely separate from the one handling looping. This means total dedication to the sound you want to get and the cool ability to add delay to your loops.
Level The Playing Field
Change how loud the loops that are being played back to you are. Turn clockwise for maximum you, counterclockwise for a more conservative approach.
Delay’s Delight
15 delay types are at your disposal, all done in world renowned TC quality. Have a look, you know you wanna try them.
Room To Rock
Flashback X4 is equipped with four TonePrint slots, allowing you to load your favorite signature delay effects as done by the artists on the TonePrint roster. Oh, and since this is the 21st. century, you can load TonePrints via your smartphone.
Loopy For Creativity
Flashback X4 has a 40 second looper so you can jam to your heart’s content, and they've added an ‘undo’ function to speed up workflow and increase fun.
Simply Delay
Flashback X4’s controls and I/O options are aimed at one thing: making life easier for you. Dialing in sounds, loading TonePrints and integrating it into your set-up is a synch. There’s Mono and Stereo options and even an expression pedal, allowing you to control any delay parameter available.
Time For Tones
Turn this dial all the way down for really short repeats. Turn up until you find your preferred amount of delay. Turning it all the way up will give you a whopping seven seconds of delay time in most modes.
Ember To Inferno
Subtle to screaming, this is the knob you rely on for setting the volume of your delay level.
Positive Feedback
No, this is not the Marshall-like squeal we know and love, but it does allow you to set the number of repeats you want from short and slappy to total timewarp.
Mix And Match
The subdivision selector on Flashback X4 allows you to choose quarter notes or dotted eights, but has a nifty feature that allows you to select or mix either/both when using dual delays, adding flexibility, creativity and unexpected results!
