A Designs KGB-II Instrument Preamp

The A Designs KGB-II Instrument Preamp is designed to provide a +4dB transformer balanced line-level output. Plug in your guitar, bass or keyboard directly into the KGBs (Keyboard/Guitar/Bass) and they will directly drive line level inputs of DAW interfaces, effects processors, power amps and line inputs of recording or FOH consoles without the need for a microphone preamp. With the A Designs KGB-II Instrument Preamp, there is no need for DI/Direct Boxes or Mic Preamps.

The A Designs KGB-II is a dual channel device with two independent instrument pre-amplifiers in one box. This gives the A Designs KGB-II great flexibility in many applications like; stereo output keyboards, two different instruments at one time and stereo guitar effects pedals to name a few and by cascading one channel into the other gives an even wider range of options.

To accommodate any instrument, the front panel of the A Designs KGB-II features High/Low Gain toggle switches and Switchcraft 1/4-inch Input and Thru Jacks. On the rear panels are balanced XLR output connectors and toggle switches for phase flip, ground lift of XLR Pin 1 and power on/off. The KGBs are each powered by an external wall transformer of 20-24VAC (supplied US only). A modified voltage doubler circuit is used for generating the regulated +/-24 volt rails that powers the custom designed discrete “Class A” operational amplifier modules. Both models chassis are built of solid steel for durability. Made in the USA.

The use of CineMag output transformers allows for the use of long transmission line feeds through balanced output cables as for live sound applications. In addition, both KGBs are optimized for guitar and bass guitar pickups impedances, as well as the unbalanced outputs from electronic keyboards such as vintage synthesizers. Operation is simple and immediate for either unit. The High/Low Gain toggle switch sets the operating range depending on what source you plug in, and a single aluminum knob sets the final output level.

In the studio or on the stage, the A Designs KGB-II is of a “no frills, no compromise” audio philosophy for pure sonic capture and reproduction.
