The Zoom A1X Four is a multi-effects processor built for acoustic instruments, one of Zoom's A1 Four and A1X Four pair, available from October 20191. Like the G1X Four, the A1X Four adds an expression pedal, which brings 8 additional pedal-controlled effects to adjust volume, pitch, reverb, delay, and wah12.
What the expression pedal adds
The A1X Four comes with 8 additional pedal-controlled effects to adjust volume, pitch, reverb, delay, and wah, according to Zoom's product page2. In practice that means the onboard pedal can be rocked to sweep a wah, swell the volume, bend pitch, or blend in reverb and delay while you play, hands free. Zoom describes the pair this way: "The A1X FOUR comes with 8 additional pedal-controlled effects to adjust volume, pitch, reverb, delay, and wah."2
Gearnews, covering the announcement, put the difference simply: "Like the G1X Four, the A1X Four adds an expression pedal."1

Where it sits
The A1X Four is a multi-effects unit rather than a single-purpose pedal, so it covers ground that players otherwise fill with several boxes: reverb, delay, wah, pitch and volume control in one unit2. Players comparing it against single-effect acoustic pedals, such as the Fishman AFX AcoustiVerb for reverb or the Fishman AFX Acoustic Delay, will find the A1X Four bundles those effect types together, with the tradeoff of a menu-driven multi-effects workflow instead of one-knob simplicity.
