Any body use the MXR noise gate pedal? I'm using a rocktron rackmount noise gate now in my rig but it only works well running my guitar into that first then into the input of my head. It does color my tone a bit. I've tried it threw the effects loop but it doesn't work to well like that, seems like it works perfect threw the effects when my gain is off, also threw the effects loop it doesn't color the tone much at all but, it's not tight enough of a gate like that. So anybody try the MXR pedal?
