The KGB-Itf is a high input impedance, discrete audio preamp designed for high impedance, unbalanced signals including guitar, bass guitar and electronic keyboards. Just as a low-impedance, balanced preamp is a tremendous benefit for your microphones signal, a preamplifier designed for use with unbalanced high-impedance instruments is also a critical component of great sound from a high-impedance sound source.

The KGB Series contains high-voltage, discrete op-amps with balanced output transformers by Cinemag, Inc. The KGB-Itf is a single-channel, solid-state unit that works well with guitar, bass or keyboards. It features an all metal chassis, milled aluminum knobs, balanced XLR gold-pin Neutrik outputs, Switchcraft 1/4" input jacks, bipolar electrolytic capacitors, 1% metal resistors, blue LED power indicator, four rubber feet and heat vents, as well as three tone controls for high, mid and bass.
