G-System and JVM205H

New
2021-08-21

Greetings all, I have an issue. I have been using a G System in front of 2 clean amps in stereo for over a year. Incredible unit, kicking drive pedals in and out, flawless, incredible sound. I have just purchased a JVM205H head and wanted to use the full MIDI implementation and the effects loop on the head with the G System, I'm getting MIDI controller changes to the head, it will insert pedals when I want, but none of the modulation effects, delays, reverbs or anything else is making it to the head. I'm using the 4CM in the loop, I've tried the series and parallel both and nothing. It sounds terrible going straight into the input so any help will be greatly appreciated. TIA
