This unit is in full working order and good condition,  apart from marks from being slid in and out of its rack space. It has always been rackmounted in my studio. Sold without any extra plugins beyond the normal ones supplied for a new account.

The 'push to mute' does work, but requires a 'decisive' push. The volume pot works absolutely fine though. Both can be operated via software too.
