According to Mesa Boogie Tech dept, these units require an isolated ground connection for each of the rear panel 1/4" external switching inputs.Since Y-Split cables are sharing the ground, they cannot be used from the G-System or G-Major (which output connection is TRS) because they could cause damage to the amp switching network.
The G-Major does have relay switching, however its use with Mesa/Boogie amps is not recommended because of a shared ground (can diminish the quality of the amp).
Just a couple of comments I find browsing...can someone clarify the issue with G-major relay switching and Mesa/boogie amps, specifically the Rec pre (which has two 1/4" jacks on the back for ch1/ch2 and solo on/off)?
