Taylor Acoustic BBTE w/ gig bag in very good condition comes equipped with Taylor ES-B™ acoustic electronics, which blend Taylor’s proprietary pickup design with an onboard preamp that features a built-in chromatic tuner, Volume control and 3-band equalizer (EQ). (If your guitar features the pre-2022 ES-B design, you can view that guide here.) The ES-B enables you to plug in your guitar and enjoy great-sounding amplified acoustic tone. The built-in tuner makes it easy to tune your guitar anytime, anywhere. The Volume and EQ controls allow you to shape your tone to suit your personal preferences. Together, the ES-B components give you an all-in-one system for a seamless plug-and-play experience.
