80's Rats have a more mid dip by their BIAS resistor
Newer Rats are crap, utter crap. I've seen too much of em on my bench to mod em and they all differ in parts, quality, etc.
Worst issue: some of em have reverse log potmeters......... WHY????? By using these potmeters you can not dial in any nice tone and the volume knob goes from no sound to full in 1/10th of the turn.
Tijd zat..., toch?
