I'm leaning towards just getting the prepainted figures but that chasm fiend is so damn cool, gotta have it but I'm worried I'll ruin it if I try to paint it myself lol

I've been learning for the past 6 months or so, but I've only really played using Neural DSP and nothing else. I have no idea how to adjust amp/effect settings to make a good tone, with either analogue or simulated equipment, so I mostly just use the presets. I usually am playing through Archtypes Cory Wong, Plini, or Gojira. I've searched for tutorials but usually they just explain what every knob/setting does, they don't really explain how to make it sound good lol. Any points in the right direction would be much appreciated =)
