I am really into heavy distortion. I have seen pickups with built in distortion. How good are they? Can you turn them off and on? Do they make nasty sounds when hooked up to another disortion pedal or do they make a better distortion? What are the best (quality and financial) ones out there? How could I arrange them to get a deep gutty distorion? I have two pickups. Should I mix 2 distortions, a distortion and a deep toned pickup, what? AHHH! I don't have a clue when it comes to pickups. Help me, please!
