This device is model no. GVS008 and is the first in the series to feature an external video input, and custom CNC’d front & rear panels. This machine is similar to The I.F.D. in terms of feature set, minus CV implementation and + the video input. The input allows this model not only to function as a synthesizer and internal feedback generator, but as a loopback for use with video mixers, and as a standalone glitchy video FX processor similar to the VGS35 & GVM002.
The I/O includes a composite video output, composite video input, a VGA output, an external audio input (1/8” and 1/4”), and a standard 2.1mm barrel jack for a 5v power supply.
