Hey guys, I use a Digitech RP 90 and a Marshall 15CDR amp.But the distortion of the processor sucks (or i dont have proper patches). Im not able to get nice Megadeth, Pantera tones. So my question is that can i use the RP 90 (via the OD Channel of the amp) and get my distortion from the amp (and later get a MT2 or AMT metallizer) and use the noise gate freature,wah,whammy of the processor?? In "AMP/Distortion" there is a setting called "Off" , will that do my job? I can get good megadeth tones from my amp in OD about by axe is crap so its noisy and i need a noise gate..
