Through the various modeling options, this Zoom interface allows the acoustic instrument to take on another dimension thanks to the different types of chorus and flanger. The A1 Four FX Pedal appears to have a plastic construction but its coating is hard and heavy and this makes it robust and durable. With regard to sound, it is capable of generating different types of tones depending on the user's experimentation with the different options of chain effects. I use this pedal outdoors, because it works with 4 AA batteries it becomes an excellent option for street performing.
The strengths of this pedal are the diversity of options that range from integrated looper, modulation effects, simulation of different guitar bodies, distortion, simulation of tube amplifiers to drum machine. It is unfortunate that the looper has only 30 seconds in its duration and the integrated batteries have a somewhat robotic sound, which are the weaknesses of this pedalboard. However taking into account the options that it presents in relation to its price, it makes it a good choice for any acoustic player.
