According to LA Sound Design, the Boss FV 300L was added to Tim Mahoney's overseas touring rack replacement board.

"The board is set up so that he can run a Volume pedal and Nova Delay in the loop of his Dist amp and a Volume pedal, Nova Delay and Nova Reverb in the loop of his clean heads in stereo. A custom power supply was built as well as the custom interface with Jensen ISO transfromer. Tim will use this along with his giant board in front of the amps."
