The KGB-Itf are single-ended, high input impedance, discrete audio pre-amps 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. 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.
The KGB-Itf also includes three tone controls, High, Mid, and Bass.
- Single Discrete Input with Thru
- Gain Select Switch - High/Low
- Phase Reverse Switch - Ground Lift Switch
- External Power Transformer for a very low Noise Floor
- Three Band fixed frequency Tone Filter with 12db cut/boost - High/Mid/Low
