A Designs KGB-II
Dual Channel Instrument Preamp
The KGB-II is a single-ended, high input impedance, discrete audio pre-amp designed for high impedance, unbalanced outputs such as: guitar, bass guitar, and electronic keyboards.
Just as a low impedance, balanced pre-amp is needed, (designed for use with microphones), a pre-amplifier designed for use with unbalanced high impedance instruments is also required. The KGB Series contains high voltage, discrete op-amps with balanced output transformers by Cinemag, Inc.
The KGB-II is a two-channel, solid state unit that allows use of both channels for stereo recordings or live performances. This works well with stereo output instruments such as: keyboards or stereo guitar pickups. For bass players, there is freedom to use two basses in a live performance, simply by picking up the other bass and playing without any delay between songs.
