Faithfully replicating vintage specs, these are high-quality, hand-wound pickups designed with Fender's 1969 pickups in mind. The '69 model is famous for the Fender Custom Shop '69, and these pickups seem to be designed to reproduce that sound. In particular, the bobbin and coil colors faithfully replicate the "Fender Custom Shop '69" limited edition pickups signed by Abigail Ybarra. (The specifications seem to be slightly different from the current Fender Custom Shop '69.) Detailed specifications: Alnico 5 magnets, enamel wire, Wax-coated push-back lead wires, Black top and gray bottom vulcanized fiber bobbins, and staggered pole pieces. Wax coating is a mix of paraffin and beeswax. There are no modern settings, and the middle pickup is not R.W.R.P., It's a setup designed to embody a truly vintage sound. Recommended for those seeking that kind of sound. There is no distinction between neck, middle, and bridge pickups, so it's best to put the ones with lower output on the neck side. The measured output of several actual pickups I've handled was: Neck: 5.7〜6.2k Middle: 5.7〜6.3k Bridge: 6〜6.38k These are just guidelines and may vary depending on the individual pickup. (Estimated values: Neck: 5.8K, Middle: 5.8K, Bridge: 5.8K) The Fender Custom Shop '69 is known for its slightly low output, and these pickups seem to reproduce that sound, offering a different sound from Texas Specials, etc. By the way, the cover size is 52mm for all positions. Vintage white covers, mounting screws, and tubes are included. The lead wire length is approximately 210-220mm for all. Fender Custom Shop '69 sets can be quite expensive, but it might be a good idea to try these as a replacement.
