Hi. I'm running a marshall valvestate stack and I use a gt-8 in 4CM (amp FX loops)and use an MXR micro amp before the cab for solo boosts.

My question is, where do I add a MT2 stomp box in the connections? I'd like my heads preamp but I want some more chunk for metal tunes.

On a few tunes I need more meat n potatoes gain then my amp has and I dont use any OD/dis on my gt-8 because I get terrible feedback for some reason....which maybe someone has a cure for??

Anyway, I'm just looking to get that low end wet tone from an MT-2 without the feedback and use the gt-8 as well.

I'd RATHER use one of the OD/dis settings but the feedback as soon as I engage is bad even with my hand on the strings.
