The Lace Sensor pickup has been around since the mid 80s and they were used exclusively by Fender Guitars up until the mid 90s. Lace Sensors were standard equipment in many of the high end Fender guitars for years. Many country players swear by them. Many rock and blues players use them also, such as The Edge from U2 and Eric Clapton. Eric Claptons signature guitar comes with Lace Sensor pickups standard from the factory. The Lace Sensor is a unique pickup because it has a special system that reduces the typical single coil noise. Lace calls it their radiant field barrier system. Lace states that their pickups generate 36 seperate magnetic sensing fields in which it can detect the string vibration. These fields are then heavily sheilded to reduce the noise that you typically associate with single coil pickups. Due to their unique design the Lace Sensors can pickup a greater physical area on the string. All while detecting less outside unwanted noise. Because the pickups are so efficient in picking up the string and not the noise the pickups can use less powerful magnets. Because the magnets are less powerful this reduces the string drag and string pull effect the pickups have on the strings. String drag is when the magnetic field of the pickup effects the string and causes the sustain of the string to decrease. String pull is when this magnetic field changes the pitch of the string. The standard Lace Sensor pickup is the Lace Sensor Gold. The Gold has an output of 5k and is ideally suited for classic rock as it is a replacement for a standard Fender single coil. The Lace Sensors are mostly sold in 3-pack sets. These sets are intended to replace every pickup in a standard Fender guitar. If you are looking to increase the sustain on your Fender guitar and give it a fatter tone Lace Sensors may be the way to go.
