"This is an Oberheim SEM on the inside, originally marketed by 360 systems for the guitar market. This one was MODIFIED for CV Gate control (it’s not set up for use with guitar).

This unit was meticulously serviced over 10 hours to work like new again, no typical lies or excuses, making this unit better and more valuable than others you may find. Power supply recapped. Molex connector terminals replaced. VCO VCF VCA recalibrated. All pots and switches properly cleaned and lubed. Modified (see below). Audio input added. Cleaned inside and out.

Note: The latches that hold the lid in place are broken and we didn't have a source for replacements.

This 360 Systems Guitar Synth came to us without a guitar pickup (they're usually broken, when they're present), so we had our tech modify it for use with CV and gate from any compatible CV gate devices (including most if not all available midi to CV converters). He also modified it so there's full control over the VCA envelope generator, adding 2 potentiometers for the 2 envelope control that are missing from the stock Spectre in the place of 2 1/4" jacks that aren't needed when using it without a guitar. Since this unit's not set up for use with a guitar, the left side controls have no effect (string related stuff, octave select and transpose settings). We also need to make it clear that since we couldn't test the guitar related stuff, we have no idea whether the guitar section would work if you had a pickup, so are selling this unit strictly as is. If you plan on trying to use it with a guitar and pickup, please realize this. All other controls for the synth section are working perfectly and play beautifully via the CV and gate jacks."
