Here's the gist ....
A mono signal ( from a guitar preamp ) is sent to the Tri-Stereo Chorus which splits it in stereo L & R dry & wet ….
The left wet and dry signals are sent to a Yamaha SPX-90 in parallel, programmed to provide stereo detuning.
The right wet and dry signals are sent to the 2[SUP]nd[/SUP] Yamaha SPX-90 in parallel, programmed to provide the Stereo Hall Reverb.
This entire mix is then sent in stereo to the second stage of the routing mixer and then to 2 Lexicon PCM-42 digital delays in parallel.
One side of the Stereo mix is also sent to a Lexicon PCM-70, set to the Circular Delays preset, also in parallel.
There's also some compression from a dbx160 thrown in for good measure ....
