When you're ready play live, the PRO-1 Ultra can plug into any size PA or amplifier with the Shadow® Performer™ preamp and NanoFlex™ pickup system, the same pickup system found in Epiphone’s legendary Masterbilt guitars as well as many other classic Epiphones. The PRO-1 Ultra also features a Solid Spruce top for superior sound with beautiful 5-layer Ivory and Black binding just like Epiphone’s vintage classics along with all of the PRO Collection's breakthrough innovations. Epiphone, one of the world’s oldest and most respected guitar makers, has just made playing and learning guitar easy for everyone.
