ISP Decimator
Auto technica uhf wireless system

With this rig i want to get the best hardcore/metal tone like whitechapel, mychildren mybride, tdwp, etc but my issue is the feedback and i just got this wireless sytem and it is sketchy

what should my amp settings be and please someone help me with the decimator, it blows ass it will either cut off my sound completely or it will leave crazy feedback when i turn it up to gig volume
whats your signal line look like?

Also the valveking isnt really a metal amp unless your boosting it...

the eq pedal can get the valveking to do metal for now. and i dunno the signal i have the eq pedal going striaght thru the amp and the noise gate in the effects loop
