I record using the S/PDIF output set to "Stack" and the Main Outputs set to DEL/REV Wet for recording the guitar ambience to it's own stereo track.
I use the Graphic Equalizer in the first FX slot after the STACK to shape my tone, but it doesn't get recorded to the s/pdif output when set to STACK.
All effects turned on in the Effects section get routed to the REV/DEL output, so I lose my post amp EQ when I go to record the effects separately.
It would be great to have the same 8-band EQ with high/low filters placed after the amp and cabinet, that can be recorded as part of the STACK.
Someone please chime in if there is a way to do this that I'm not aware of...
