Description

John Mayer is one of the most gifted guitar players of his entire generation – not to mention his talent as singer/songwriter too!

Electro-Acoustic

Electro-acoustic guitars are acoustic instruments fitted with built-in pickups or microphones that allow them to be amplified or connected directly to a PA system or amplifier. They retain the natural acoustic tone and feel of a traditional acoustic guitar while adding the convenience of onboard electronics.

They are commonly used for live performance and recording, especially in situations where consistent volume and clarity are needed. Electro-acoustic guitars often include controls for volume and tone, and sometimes built-in tuners, making them a practical choice for gigging musicians who want an acoustic sound with modern flexibility.
