The Yamaha THR5A is a 10 watt, portable modeling amp designed for use with any pickup-equipped acoustic guitar or Yamaha's silent guitar models. It replicates the tone of an acoustic being picked up by various types of mics, including a nylon string and clean electric setting, with onboard effects such as chorus, delay and reverb on hand. 

The THR5A can be powered with 8 AA batteries if needed and has full USB connectivity for direct-to-DAW recording.
