Strymon Timeline

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.

HornFX Review

Interface:  4.5/5
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.

Versatility: 4.5/5
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.
