The Zoom A1x Four Multi-Effects Processor gives a range of instruments a new lease of life. Use the effects and expression pedal take your acoustic guitar saxophone trumpet violin or harmonica to the forefront of any performance. Alternatively use the intuitive modelling technology to subtly blend your instrument into group performances. Dedicated effects respond differently to the playing style of each instrument. This allows you to perform naturally and leave the A1X to work its magic. The expression pedal can be used to control effect parameters volume and wah effect. The combination of the built-in looper and over 60 drum rhythms to perform with mean you can now fit an entire band in your rucksack.
