Guitar setup (easycore, punk), which pedals?

[Jazz Noise]

If you're having noise issues, I feel bad for you son. I've got 99 probl-

Sorry, getting sidetracked. Noise gates aren't something I recommend really, unless you've set your gain stupidly high or your rig is noisey - noisey PSU/FX unit, bad shielding/cabling or bad pickup wiring.

My main suggestions are gainstage properly and be quick on your feet. Avoid adding treble after adding gain (A la my Big Muff w/ Tone Wicker, which sounds awesome but easily doubles the loudness of noise with the Tone Wicker engaged) and avoid OVER-distorting things to mask playing. You'll actually be surprised how much you can pull back on the distortion in alot of situations - I only ever jam the gain even close to 10 for insta-feedback sounds.

But I wouldn't even worry about this stuff until you hear it. If it's noisey, fix it. If it's not, don't worry.

My 6505+ let's out a pretty nasty hiss part of the reason that it does this is because of the 6 12ax7s in the back some amps hiss naturally due to such high gain too. Sorry if it doesn't help

I don't think you'll need that EQ. Try without it first.
If you only use one overdrive pedal, maybe the noise gate is not important...
