Here's what Lollar say about the Imperial Low Wind pickups:
Based on lower output PAFs often found in vintage 335s, this pickup boasts a brighter overall tone compared with the standard Lollar Imperial®. This results in exceptional definition for any chord voicing and overall great presence for cutting through the mix. You'll also find the bottom strings hold together noticeably longer without distorting than most humbuckers.
The low wind is ideal for the occasional Les Paul that sounds darker in the neck position, or for guitars with darker tones in general. This pickup is also a good match for amps that are heavy in the mid-range, or if you're seeking a clear and tight bass tone.
Made with Alnico 2 magnets in the neck and Alnico 5 magnets in the bridge that are degaussed to specific levels unique to the neck and bridge positions. Covers are nickel silver. Sold as singles or as sets, and comes in a wide range of cover options. Single conductor braided shield lead wire and 4 conductor lead wire is available.
