Fishman Aura Spectrum DI - Legendary Preamp DI for Acoustic Guitars and Electric-Acoustics I used this with a 100% blend for electric-acoustics with strong piezo pickup sounds like Ovation, and around 40% for more natural-sounding models like Taylor. It also features a tuner, compressor, and EQ, making it ready for both live performances and recording sessions. This is a classic, renowned acoustic guitar preamp. Includes the main unit, box, included CD, and USB cable.
