Jam-packed with acoustic-optimized effects — and more

The Zoom A1 Four is jam-packed with more than 80 effects — 35 of which are tailor-made for specific acoustic instruments, including acoustic guitar, saxophone, trumpet, violin, harmonica, and acoustic bass. With the A1 Four, you can turbocharge your performances with distortion, chorus, wah, and more. Building patches is a breeze, thanks to Zoom’s Guitar Lab software. Playing live with the A1 Four is just as effortless, with two performance modes, hassle-free microphone connection (including phantom power for your condenser mics), and an anti-feedback filter. You also get a built-in drum machine with 68 rhythm patterns and a 30-second looper!

Achieve studio-quality acoustic guitar tone onstage

Your live acoustic guitar tone will sound better than ever, thanks to the A1 Four. Acoustic emulation and modeling add depth and dimension to your sound. The A1 Four employs impulse responses to emulate the sonic fingerprint of a whole slew of popular acoustic guitars, enabling you to replicate your studio tone onstage. You can then shape your sound further with Gain, Bass, Mid, and Treble controls. You can also optimize the A1 Four’s processing to accommodate piezo or magnetic pickups. The A1 Four includes 15 factory presets for acoustic guitar, and 13 more are available via Zoom’s Guitar Lab software.

Elevate your violin and double bass to new heights

If you have the A1 Four, then Jerry Goodman–esque violin tones are right at your fingertips. Transform your violin into a full string symphony. Tear through explosive distorted solos. Best of all, the A1 Four’s violin-tailored distortion effects preserve your bowing attack, which is essential for expressive playing. Acoustic double bass players can get in on the action, too. Whether you play classical, rockabilly, or symphonic metal, the A1 Four yields the focused highs and rich lows you need to deliver an earthshaking performance.

Add new soundscapes to sax and trumpet

Running your saxophone through the Zoom A1 Four gives you access to a whole horde of exciting soundscapes. Gritty, rock ‘n’ roll sax growl? It’s in there. Double-tracked jazz fusion-style textures? It can do that, too. You also get EQ and compression for maximizing your instrument’s impact.
