| Another "flaw" might be that the original Moog ladder filter had resistors connected from the common base of Q22, all the way down the ladder, and eventually connected to ground. Where as the TB303 and x0xb0x uses a single resistor, and connects that to a capacitor and then ground. | Another "flaw" might be that the original Moog ladder filter had resistors connected from the common base of Q22, all the way down the ladder, and eventually connected to ground.
