The OPUS-4 is a 100% hand wound humbucker resulting in a very superior sound quality compared to a machine wound pickup, the sound is incredibly responsive and dynamic like a mix of a single coil and a humbucker.
The OPUS-4 is made of Alnico 2 Magnets and American Made Plain Enamel copper wire and it’s available in chrome, gold and the new Worn Nickel Cover (with no logo).
