Will this work?
GCP bottom 1-4 buttons
1 Preset = Rhythm.
2 Preset = Lead #1.
3 Preset = Lead #2.
4 Preset = Clean Channel w/chorus.


1-3 from gmajor2.
4-4 from gmajor2 and marshall dsl100hr using gmajor2 relay switching feature.

Any info on how to set this up or the correct way to do it would be appreciated.
