A Designs KGB-Itf
Mono Instrument Preamp & EQ
The KGB-Itf 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-Itf (Tone Filters) is a mono unit. It has the same features of the KGB-II, but includes three tone controls, High, Mid, and Bass.
