Designed to provide 60W of amplification through its 1x8" twin-cone speaker, the Compact Mobile from AER is a two-channel, battery-powered combo amplifier geared toward acoustic guitarists playing in outdoor venues—or indeed, any locale without available power. It's modeled on AER's Compact 60, giving you dual-channel operation quite suitable for singer/songwriters on the move, with independent tone sections for your guitar and your voice.

The front panel provides you with a conventional 1/4" instrument input for channel one, while channel two utilizes a combination jack and thus allows for both XLR and 1/4" connections. Channel one provides gain, bass, middle, and treble controls, as well as a high/low selector to suit various types of pickups. Also, the Colour button activates a tone-shaping filter, changing the relationship between the midrange and high-end frequencies. Over in channel two you'll find gain, bass, and treble controls, as well as a selector that allows you to choose between mic and line inputs.
