Here is my G2 stereo rig using dual H9’s, one for stereo and one for pre/post. This is so versitle and easy to use. The stereo from H9 is amazing thru this rig. Im sure it would work for othe controllers as well….. f.y.i..I use metro amp instrument level loops in both amps. If anybody has questions about this let me know, maybe I can help someone out with a similar rig.
