  • Rich Stereo Sound
  • Travel Friendly
  • Strum, Sing, and Jam Along

  • If you're new to the world of acoustic guitar and would like to explore an extra dimension in sound, creativity, and convenience, the new MOBILE AC is your perfect amp. Optimized for acoustic guitar and designed to travel, the MOBILE AC delivers big sound in a package that can easily fit into a backpack. The amp can be used for up to 15 hours at a time via battery power, so you can take it anywhere. Simply plug in your acoustic guitar, turn up the volume, and enjoy clean, clear, and surprisingly powerful, spacious stereo sound from a compact amp. You can also add deep stereo chorus or lush reverb effects, and you can incorporate a portable media player and microphone for sing-along fun. Strum your guitar and sing, play along with backing tracks, and enjoy the MOBILE AC at home or outdoors. It's also a handy personal monitor for use on stage, with a big sound that defies its small size.


  • Five-watt (2.5+2.5) stereo amplifier for acoustic guitar
  • Simple, intuitive controls
  • 15 hours of use with six AA alkaline batteries
  • Microphone input for singing
  • Audio inputs for playing along with portable media players
  • Three-channel mixer with individual volume controls for microphone, guitar, and audio input
  • Chorus, Reverb, and Wide effects to add depth to your sound

    Rich Stereo Sound
    The MOBILE AC is small, but its two 4-inch speakers produce a surprisingly large and lush stereo sound. Activate the built-in stereo chorus -- an effect that Roland is famous for -- and immerse your guitar in a pool of thick, swirling sound. There's also onboard reverb with a dedicated control knob, as well as a "Wide" effect for adding spaciousness to the sound. For the final polish, turn the TONE knob clockwise for a brighter tone, or counterclockwise for a milder sound.

    Travel Friendly
    Small enough to fit in a backpack and light enough for a child to carry, the MOBILE AC is ready to travel. Take it anywhere you go -- to a friend's house for a jam session, to a small outdoor gathering such as a camping trip, or on stage for use as a personal monitor. It can run for 15 hours at a time on six AA alkaline batteries, so you can perform in any location, indoors or out. An optional AC adapter is available should you prefer to plug it in. A handy carrying strap is included, and an optional carrying case is also available.

    Strum, Sing, and Jam Along
    Strap on your guitar, invite a friend, and grab a microphone -- the MOBILE AC has inputs for guitar and mic with independent volume controls for each, and you can even add lush reverb and "Wide" effects to the instrument and voice for a polished, professional sound. There's also a third input (with dedicated volume control) for connecting a portable media player such as an iPod, giving you an easy way to add backing tracks to your performances.

      Truly Great and Awesome

      Posted by Unknown on 11th May 2017

      I bought this based on all the great positive reviews on every online retailer I could find. Not only that, it truly lives up to all the positive reviews.
      My own thoughts are that it's an amazing little gem.

      I got it for my ukuleles and it works amazingly well.
      I've got a MiSi Acoustic Trio pickup on one tenor, and an L.R Baggs 5-0 pickup on a Cordoba Tenor, and a Fishman pickup on a larger Cordoba GK Studio acoustic guitar. All work great with this amp.

      Super portable, and very very well built. Feels rugged and great quality.
      Tone is superb for the size! Very low noise or next to none.
      Clean clear acoustic tone.
      All the extra stuff are huge bonuses like the Reverb, Chorus, Wide effect,
      and even the ability to plug in extra inputs like Microphone for singing, Line in for Keyboards or play along MP3 Player, and i think that extra line in can also be used for a 2nd uke or guitar input if patched correctly.

      Fantastic amp for practice and performing in small venues.
      Love it!!!
