Acoustic guitar modelling Acoustic guitar modelling helps add depth to your performance. This not only helps bring solo performances to life but can be used to seamlessly integrate into group performances. With the A1 Four, you can have your live performances sounding like a studio recording. The A1 Four achieves this with intuitive technology that varies for each instrument’s characteristics. For acoustic guitar, 15 factory presets give you all the characteristics of highly sought-after guitars. Modelling everything including the body shape of the guitar, you are able to apply specific EQ’s dependant on your guitar’s pickups. Warm and rich tones are available whether you’re looking for an unplugged performance sound, or finger picking country and blues. More presets are available within ZOOM guitar lab. Give your sax some rock and roll growl The A1 Four allows you to play naturally and adapts the effect to your instrument, ensuring all the power of your performance is captured and backed up with authentic effects. Customisable chorus effects can be used to emulate a classic jazz fusion sound. This utilises the A1 Four’s ‘SaxChrous’, a natural double track to help bring your saxophone to the forefront of live performances. EQ’s and compressions dedicated specifically to saxophones make it easy to develop your sound with the A1 Four. Trumpets, violins and more The A1 Four caters for trumpet players by adjusting the effect to your playing intensity. Low-pass filters are also applied to ensure the effect remains constant across your full playing range. One particular effect, the auto wah, will bring life to your performance whilst remaining tuned to your trumpet. The A1 Four uses different approaches to tailor violin and upright bass effects to your instruments. Responding to your bow, violin effects feature balanced saturation thanks to a unique frequency response across the entire range. By reducing the lows and raising the highs, the effect remains constant throughout your performance. More body for your harmonica’s soul The presets provide you with instant access to authentic sounding effects, with the A1 Four layout designed to make customising these simple. For harmonica, punchy blues sounds instantly transport you to the bars of New York. Other presets include the ‘Hm StevieW’, giving you the notorious harmonica sound of the legend himself. Avid harmonica players will be aware of the green bullet microphone, widely regarded as the best harmonica microphone available. The A1 Four ‘Hm Juke’ patch can give your current microphone the green bullet treatment. Become your own band ZOOM Guitar Lab is free software that allows you to customise effects using your laptop or computer. These can then be placed on your A1 Four via USB. The built-in looper, allowing recording up to 30 seconds, means you can create an entire backdrop to your instrument. Mix this with the 68 drum patterns and you’ve got yourself a band. Anti-feedback technology makes all of this possible whilst reducing frequencies likely to feedback. MAA-1 The included MAA-1 adapter can be used to connect a microphone to the A1 Four. By providing phantom power, you are able to use either dynamic or condenser microphones. Loudness control and a peak indicator allow you to adjust gain settings prior to reaching the A1 Four.
