Designed in collaboration with jazz guitarist Al Di Meola and acoustic rocker Melissa Etheridge, the OP-Pro with XLR combines state-of-the-art audio quality with exclusive features designed to meet the needs of professional guitarists. The easy-to-operate unit offers 3-band EQ, a preset tone enhancement circuit, and a chromatic tuner. The XLR jack provides a balanced line connection to mixers, recording consoles, and high-end acoustic amps. It also provides phantom power to the OP-Pro—an essential feature for stage performers and touring professionals.
