DiMarzio doesn't just imitate the late '50s humbucker sound by using Alnico 2 magnets or aged Alnico 5 magnets. Airbucker technology was developed to achieve the ultimate sound quality of vintage humbuckers while solving a number of difficult technical problems. While it has the sweet tone characteristic of vintage humbuckers, Airbucker technology allows us to take advantage of the strong magnetic properties of the Alnico 5 magnet while reducing its impact on string vibration, thereby improving sustain and sensitivity. The result is a three-dimensional sound that accurately captures string vibrations while maintaining sustain. This expressive sound gives players endless possibilities.SPEC Output 206 Treble 5.5 Middle 4.5 Base 5.5 DC resistance 8.34k Magnet Alnico 5 Conductor 4 Air Backer Technology Standard-Spaced & F-Spaced DiMarzio full-size humbuckers come in two sizes to accommodate different guitar specifications. Generally, Gibson guitars use a standard pole piece spacing of 9.7mm, while guitars equipped with synchronized tremolo or Floyd Rose guitars use a 10.2mm F-space. The above may not apply depending on the specifications of your guitar and the position you want to install it in. We recommend that you measure the string spacing in the position you actually want to install it in before placing your order. ■The tone guide shown is the manufacturer's reference value. ■The image is a sample.
