Yamaha brought their new acoustic guitar to the Birmingham store, with a secret hidden weapon. An actuator installed on the inner surface of the guitar back vibrates in response to the vibrations of the strings. The vibrations of the actuator are then conveyed to the body of the guitar, and to the air in and around the guitar body, generating authentic reverb and chorus sounds from inside the body.
