The normal bass has # 1) 250 ohms potentiometers and a .047 micro farad capacitor. To go deeper we use # 2) a .10 cap and 250 ohm pots. Let's go the other direction and use # 3 ) a .022 cap and 500 ohm pots. What is the sound of each and are there sound clips somewhere accessable? what actual use would # 2 and # 3 be good for?
