The Gigpro is a single-channel belt-clip preamp that will work with most pickups. It also provides 9v phantom power for mini-mics and other phantom-powered onboard electronics. Based on the Para D.I.'s award-winning circuitry, we have pared the features down to the essentials -- nevertheless, it has everything necessary to get the best possible sound from your pickup. For example, the two-band EQ and variable low cut is amazingly flexible and intuitive to use.
