The Slavedriver uses a hex pickup (installed on your favorite guitar) to channel guitar notes to the main unit which converts your playing into range of control voltages to interface with your favorite monosynth.
The Slavedriver features 1/4in CV/Gate outputs for: guitar, pitch, loudness, trigger. There are controls for octave range: 2, 4, 8, 16, 32; and footswitch interval. There are also 1/4in inputs to connect footswitches (not included) to control sustain and transpose hands-free.
Internal dials allow the user to adjust each string’s sensitivity. Once you get pickup situated on your guitar, and patch the Slavedriver into the cv and gate jacks on your synth, you can have hours of synth guitar fun.
This particular unit is good shape, and works well. The pickup as been hard-wired to the cable and unit (it came to me this way), but could easily be modified to incorporate a jack for added convenience..."
