Mesa Boogie Triple Crown in Helix Posted August 7, 2017 Hey guys, I know there is a plethora of threads about 4CM on here, but my question is amp-specific. I plan on buying a Mesa Boogie Triple Crown TC-50, and I'd like to run it into the helix. It's not really going to be 4CM the way I want to do it, because I'm going to go Guitar > helix input > pre-amp fx > send 1 instrument level into TC-50 > TC-50 line out into Helix return 2 at line level > IR, followed by any other fx > out to studio monitors or L3M. I dont usually put fx between the amp and cab, which is why I'm running it without the amp's fx loop. So long story short, I'd like to know if anyone has come across any ground loop issues, or unbearable noise floor levels, running the TC-50 this way? And if I come across a ground issue, what is a decent solution box that doesnt cost an arm and a leg, and where in the chain would I place it? Sorry for the long explanation, but thanks in advance! Oh and in case you don't know the Triple Crown, it has a built in load box with an unaffected line out, which is why i will be running it this way. Cheers!
