This is the famous effects processor that provided the distortion for the Nine Inch Nails albums Broken and The Downwards Spiral.
The unit supports up to 99 patches for you to configure to your hearts content.
This unit is a early 90's digital effects processor that has a wide range of effects from various distortions to wah, pitch, flange and much more.
This unit is in great shape. The battery is healthy and even user replaceable without soldering.
The only issue this unit has is that the headphone volume knob broke off and was glued back on (before my time with it) so it works fine but the knob is a little tight to turn. It has no impact on the line outputs so unless you use the headphone jack a lot and then need to do a lot of volume changing, you'll never know it's there.
This unit has a mono in and stereo out and sounds great!
It is a half rack unit with standard center mount screw hole to mount on appropriate 1U 1/2 rack like the Roland Rad-50.
