Flashback X4 has the same delay, feedback, and level knobs as the Flashback, but with 12 different delay types and four TonePrint slots. It also contains a high functioning looper, which is much easier to use than the one in the Flashback, as the X4 has record, play/pause, and play once knobs that are absent from the smaller version. But beware. This pedal is HUGE.
External Control: MIDI/EXP/APP/TPRINT
With all of that physical space opened up, one would expect an advanced interface over its little cousin. In this respect, the X4 delivers. The dual function as looper and delay pedal are incredibly easy to use and understand. This pedal’s looper controls are quite nice. The addition of optional midi control is another game changer. It is also impressive how inviting and simple to understand this pedal is, considering how big it is.
This pedal certainly gets a versatility bump over its smaller family members due to its expanded presets and TonePrint slots. The highly usable looper gives it an extra boost as well. This is a fantastically wide ranging pedal.
Tonal Reproduction: 4/5
This pedal is another brick in the stronghold of quality tone and sonic integrity that is TC Electronics.
Live application: 3/5
Although this pedal does give you an amazing set of truly simple tools to use on stage, it is so goddamn big. The size truly does limit its usability, but that is still not enough to overshadow how fantastically this pedal would function on your board if space was unlimited.

36+ studio quality algorithms and counting - The pedal has 12 algorithm types, all with multiple variations. For example, there are 4 different tape delays on tap.
Classic Sounds - Emulations of classic tape and analog units are available, as well as our take on these types of delay.
Easy to use and fast to dial in - All the algorithm controls are sitting on a knob in front of you, no fiddling through laborious menus.
Tap Functions - Global tap tempo as well as local tempo with lots of subdivisions are available on all modes, in addition to being able to set the delay time directly with the knob.
Low Noise signal path - Features a signal to noise ratio of >104dB and maintains an analog dry path.
Dual Delay Engines - 2 delays can be used at the same time, each with its own full set of controls and routed in serial, parallel or left/right.
Up to 35 Presets - Settings can be saved to 35 presets. With three stomp switches, accessing the presets is easy.
2 Preset Modes - Bank style or scrolling style preset modes.
True Bypass and Buffered Bypass - It can be configured to run with true bypass or buffered bypass if you want to hear trails.
Cabinet Simulator - 3 variations to choose from, perfect for recording, practicing or for gigs without an amp.
Output Transformer - Get hum-free operation when operating in stereo with two amps. Output 2 is isolated with a transformer to eliminate nasty ground loops.
High Quality Audio - 48kHz sampling, with 24 bit conversion and 32 bit internal processing.
Analog Dry Path - Dry signal is left untouched, and blended with the wet signal using VCA. (no zipper noise, hooray!)
Unsurpassed Connectivity - The Universal Control Port allows you to connect an expression pedal, external tap switch, control voltage, external audio input and MIDI - all using a standard 1/4" jack!
Advanced Configuration Menu - The Advanced configuration menu lets you configure how your delay works. Select from true or buffered bypass, 0-35 presets, MIDI configuration, Control Port(expression pedal, external tap, control voltage and MIDI) as well as which style of preset system to use, input signal pad, output transformer enable and more!
Small Size - The enclosure measures approximately 5.7" by 3.75" by 1.75", which is delightfully small when considering all the features packed into this unit.
