We have found a company that produces some nice pre-amps along with some great sounding film-transducers and condenser mics which make for very elegant active systems for koras.
Installation is easy, no soldering, everything plugs together, after-market installs are no problem. Controls are mounted inside the soundhole, only one hole required for the jack (if you want to run the cable through the soundhole, you don’t even need that). The entire system is housed inside the body of the instrument. Very good installation instructions included.
Pickups can be mounted under the bridge for a clear, bright sound or on the body of the instrument for a warm, mellow sound. The dual input pre-amps let you blend both signals together.

We are currently using these three models of pre-amps:
single input, uses transducer pickup, with volume control
dual input, uses 2 transducers or transducer and condenser mic, stereo output (you can connect a stereo cable and split the signal at the amp for two inputs, one from each pickup)
dual input, uses two transducers, volume and crossover control(signals are blended onboard), mono output
good general purpose pickup, good highs, good low
bigger, good low end, we use it with A2.2XOM pre-amp in combination with AST 1470
