The Jen Syntar is - put it simple - a Minimoog rip-off for guitarists. The basic signal layout approximates the old moog. Instead of a keyboard a hexaphonic pick-up triggers two VCOs, thus making it a simple but quite powerful mono-synth. Both VCOs are capable of tri, saw and pulse/square waves. VCO2 is tuned relatively to VCO1 in order to obtain some fat detuning or those classic 5ths and 7ths. Sound is fed though a lowpass VCF (24dB/oct) before reaching the VCA. VCA and VCF have independent envelopes of the atypical ADS variety (no release).The GS-3000 Syntar is created specifically for guitar. Instead of a keyboard there is a 6-pin dim input jack on the front for the original glue-on hexaphonic guitar pickup.
