Mick wanted a tighter bass response and a top end that cuts through better and clearer. When you're playing with that much gain and power every incremental tweak becomes amplified by thousands. Like Blackouts Originals, the EMTY pickups feature a high gain differential preamp with balanced inputs. What that means is you get all the aggressive firepower of a high output active 'bucker with up to 12dB less noise than other active pickups. The main sonic differences between the EMTY pickups and the Blackouts Original are the extreme highs and lows.
